Irken Senses, And Other Ponderings

Irken senses, and other ponderings

You know, every time I start to wonder if I’ve finally run out of things to coherently say on the whole “speculating about irken biology” matter, a whole something more is induced to hatch out of the dehydrated floam inside my skull. Between you and me, I think the eggs are triggered by ironic timing.

Anywho, I’ve been thinking a lot lately about the world hypothetically through Irken eyes, and other sensory organs. Think I’ll go down them piece by piece, and to follow the pattern I’ve kept through my other Irken brain dumps, I will be drawing a huge amount of inspiration from real life arthropods. Yes, I’m very aware that realistically, any resemblance to earth insects would be coincidental from an alien species, and there’s plenty of room to make up whatever somewhat plausible explanation you can for any faucet of their anatomy. Personally, I like to run from the convergent evolution angle, since I find it no less grounded, full of potential connections the show itself all but begs me to draw, and just plain fun. Let’s get into it.

Also like towards the end there’s a whole section on the hypothetical edibility of Irkens because why not

Prelude: If you want to hear a little more behind my theory about the Irken diet revolving around sugar and a small portion of minerals, you can zip onto this analysis I did, in which I touch on some ideas of mine regarding the composition of Irken skin, their reaction to meat, etc. that works from the assumption that Irkens evolved out of an arthropod-like ancestor. Not necessary to get the gist of this one, but it is background context behind my thought process.

Sight

The Irken oculus is perhaps the most striking feature of the species, very much resembling those tiny crawling things they have been inspired by; however, it’s tougher to say exactly how far the similarity of their insides go. The eyes of most arthropods are in fact along the more simple branches of the evolutionary tree. We know that Irkens are not likely to possess compound eyes, like those found in flies and most other insects, because compound eyes are specialized for wide FOV ranges at the sacrifice of visual resolution quality. Instead, I see a much closer match to a fascinating exception or two found in Earth’s arachnids.

While most of them have utterly piss-poor vision, the hunting styles of jumping spiders necessitated a great deal of further specialization of the organs for depth perception, color differentiation, and sharp images. These are the purpose of those two huge shiners at the front (the other 6 boosting their range for detecting blurry peripheral movement and threats), and these are what bring their effective vision on a level much closer to that of familiar binocular mammals than their own six legged prey. Now I really think we are working with the base of what Irken peepers likely developed out of. One of the ways they have really diverged off is in the fact that while jumping spiders can only move their retinas, irkens seem as though they are able to move the lens of the eye themselves- or at the very least, Zim does, else the false pupils in his disguise contacts would not behave quite so convincingly. To speak about the lenses themselves, their eyes are not dry and exposed like most arthropods, speaking to a vulnerable sensitivity. They clearly have blinking eyelids, shed tears, and Zim even complains about the “scratchy” feeling of getting used to that part of his kid disguise.

(Funny sidenote: I’m like 90% sure that Zim did not have those contact lenses designed correctly for himself. Usually, if contacts feel that uncomfortable and keep falling off of the eye as easily as his do, it’s a sign of them being poorly fitted. This could be another symptom of his outdated/lower quality invader tech.)

Not only do Irkens have an assumed base vision resolution that seems more or less on par with human beings, but Invader elites are fitted with ocular implants that grant them a significantly greater advantage in this realm. We don’t know to a certainty how well improved an Irken soldier’s vision is, but Zim was confidently able, within seconds and under pressure, to pick out the area of town he lived in from what was miles away under night hours.

On the topic of night vision, I have a hunch that even without the cybernetics, these guys are adapted to see much better than we in dim to dark environments as well. Most of the early part of their life cycle is lived out in subterranean crèches. On the surface, daytime Irk is cast in a sunset red atmosphere. Oddly, a massive portion of their fashion and architectural aesthetics show a preference for these dark, warmer tones. Ruby is far and away the most common eye color in their kind. All of these facts suggest that warm-spectrum hues and pigments were incredibly common in the homeworld’s history, to point of indicating something about a cultural attraction to them- kind of like how humans put the color blue all over so much corporate branding and elsewhere. Zim’s favorite color has also been revealed to be purple. Most of all, given what I’ve seen of Irk’s, Blorch’s, and Devastis’s surface skies, AND Zim’s reaction to staring directly at the sun for more than a few seconds, I’m assuming that most Irkens are wholly unfamiliar with living in an environment as brightly lit as midday Earth.

I do think Irken eyes “glow” in the dark, but not in the emitting sense. Just more in the reflective one. This they would owe to a well developed tapetum lucidum, as seen in cats and deer and pretty much any animal to give off an eerie eye shine under the right lighting. To point back to arachnids, wolf spiders are speedy nocturnal murder machines with highly developed tapetum lucida, in their secondary eyes, at least. What I love the most about that is it makes it very easy to tell if you’re looking at a mother spider because her babies will give off the same eyeshine if you take a pic of one with the flash on.

Additionally, I won’t forget that sleep is no longer a necessity for our alien subjects. This alone gives them a major edge over any dinural race such as humanity. While Zim has his appearances to keep up during the day, the nighttime on Earth is actually when he is allowed the most free rein to work on his endeavors uninterrupted.

Sound

Ah, so this is the part where I rattle off the common theories we’ve collectively formed about Irken antennae as the replacement for an external ear, eh? Yes, but actually no…. jokes aside, it’s just no. I’ll get to the deal with antennae, but as you might imagine, hearing ability also varies all over the place in the insect world.

It is true that antennae play a large role in the hearing of some critters, such as mosquitoes, whose males use them to pick out the high frequency wing beats of nearby females in a swarm. Crickets, on the other hand, use sensory organs on their legs tuned to much lower sound ranges. There’s no one way to evolutionarily put together a sort-of ear, as well proven by the sheer amount of times it convergently happened in bugs and in how many creative ways.

They literally be designing themselves like me playing around in spore. If we’re not talking about that mosquito or honeybee example, then what we are referring to as an ear and most hearing insects is going to be an external tympanic organ. Most people who have passed high school biology would be able to recognize a visible tympanum in frogs- that circular thing right behind the eyes in most species, and understand it as their version of an ear drum. Many bugs’ tympanums are likewise thin chitinous membranes situated… potentially just about anywhere on the body (again, see above). This is what I think Irkens use as a primary hearing organ, in his case, probably situated on their heads in addition to the feelers. The latter organs I think would also be sensitive to general vibrations and subtler environmental cues, like wind direction and pressure changes, but the bulk of their hearing would be owed to the tympanum.

As far as the quality of their hearing, well, there’s not any sign it differs much from the human experience. Like us, they communicate through verbal language, and the existence of the “Dancing Arcade Game (but for aliens)” confirms at least a similar cultural propensity for music as an entertainment form. Zim is an outlier for the fact that he seems genuinely a little hard of hearing next to his kin, screaming as naturally as he talks and repeatedly mishearing (if hearing at all) people who are speaking directly at him. It’s clear something’s up with his hearing, but there’s no clear answer what and why. At first I was tempted to suggest something about sound passing much differently through the medium of earth’s atmosphere (kind of like how noise on Mars would sound muffled to us), but neither Tak nor Skoodge seemed to pick up the problem when they arrived. It really could be as simple as some kind of birth defect, or even glitches in how his corrupted PAK is processing the inputs it receives. Like many others, I want to imagine that his wig could be interfering too, since it covers the whole top portion of his head; as well, I noticed he has more of those incidents with it on than not.

Smell

Alrighty, NOW we can round back to focusing on the antennae, because this is actually the main thing our insects fine tuned theirs for. And when I say fine tuned- I mean fine tuned. Blood suckers that find their prey through the CO2 of their breath, flies that can pick up on potential food sources from miles away; In the land of the little, scent is everything. Beyond it being their main tool for exploring the environment for what to eat and what to avoid, chemical messages are the backbone of bug-to-bug communication. Pheromones are the divining rod of lonely spiders looking for a mate. They are the bugle of yellow jackets when rallying the nest to attack a threat, and they are the signals that govern about every single action an ant takes from adulthood until death. Obviously, Irkens are much more sight & hearing dependent than these comparisons, but they still have much more bodily specialization dedicated to this sense than we can relate to. For one, they are fastidiously hygienic. Like, “the care-bots from that really creepy episode of the Buzz lightyear cartoon” hygienic. We have yet to see any livable surface of Irk that is not sky to underground terraformed over in all-consuming metal infrastructure. There’s less than no sign of visible life besides the Irkens; ffs, there’s not even soil in sight. Not on Devastis, either. The Organic Sweep sounds like such a nice and pretty euphemism in the face of the actual horror of Blorch’s fate, and all to spare the boots of their military from touching even a speck of “unsavory alien filth”. They live in such a controlled and purified environment that I can’t even imagine the absolute assault on the senses Zim’s every day on our barbaric ball of dirt is. Over and over again he gives off the impression that the constant stink of this place is in fact his chief complaint about living among us. The majority of insults he throws toward humans relate to how they smell or the fact that he finds them “filthy”. We’re flat out nasty to him and I don’t blame him. Even relative to other animals, humans are especially RANK due to the combination of sweat, oils, and bacteria that coat our skin.

And believe it or not, I do think Irkens are in a position to talk shit in this regard. Zim is a really sweaty boi; however, I posed an idea back in that write up about Irken skin before- to summarize- that his kind maintain remarkably sterile cuticles due to the presence of a toxic chemical in their skin. This, I said then, could have been the key to Zim’s lice repelling trait, but I wasn’t so specific at the time about more than that. I got the idea from a group of millipedes that, when disturbed, can secrete hydrogen cyanide as a deterrent to predators. I like to imagine that Irkens can do a similar thing via sweating, not to thermoregulate like us, but as a stress response. It would at least explain why Zim seems like a very nervous sweater. Fun fact if you didn’t know, cyanide’s smell is similar to almonds.

I’m deadass telling you I think Irkens just smell like almond extract. Do with that what you will.

Touch

So, in writing this whole whatever it be, this part was the trickiest to come up with any productive analysis on. I’ve already guessed at what I think Irken skin feels most like (spoiler: hairless caterpillars) in the analysis I referenced up top. Zim being able to pass himself off as a human under the examination of the Skool nurse points to an average body temperature somewhere around our own. What I did find interesting while rewatching the series though was the sheer amount of pain tolerance on these invaders, except in one way. Can I extrapolate this fortitude to Irkens universally? Probably not! Zim is a member of the most elite of the most highly trained members of Irk’s military. I wouldn’t take what a seasoned veteran can handle and assume that’s the human floor in a nutshell, but our invaders CAN tell us quite a bit about their ceiling… starting with the fact that these bastards are ridiculously heat resistant. Irkens are a durable race broadly, but their reactions to extreme temperatures strike me as jaw-droppingly underwhelming, if anything.

Irkens DON’T like being engulfed in flames. It’s still a painful experience to them, but seemingly the kind they can pretty much walk off as soon as it’s over. Through explosions and fire we have seen Zim (and Skoodge) survive in one piece. We’ve seen The Massive take a whole dip into a burning star with no ill effects to the crew within. Most amazing to me was the time in Battle of the Planets when Zim willingly piloted Mars into grazing by the Sun at close range while trying to evade Dib. Totally exposed driver’s seat and he was no worse for wear after this.

Further in the comics we see this touched on in the Zimvoid arc. Zib’s favorite method of torturing the Zims under his training program was to torch them at random for sadistic amusement. Quite interestingly, though, Number 2 implies that their bodies do actually adapt to this treatment over time! Theoretically, Zims further along in the program have become all but invulnerable to fire entirely.

On the other hand, one of the truly most painful things Zim has been shown to experience is to have his skin chemically burned. It’s a strange sort of irony that Earth’s water would prove to be an incapacitating force to them in place of any inferno. He’ll smash his skull into the Voot’s windshield with enough force to pop out an eyeball and it’s whatever. Plenty of other things hurt, but he can power through. You turn a shaken can of soda or a bottle of bbq sauce on him and he’s just left screaming on the ground or screaming and running away. Whatever brutal sort of training he had to go through off world, it didn’t prepare him for this.

Taste

The perceptive side of this I think may not be too hard to figure out. Irken food, as alien as its actual composition could be, has been shown to be heavily analogous to human junk food. I hesitate to call what Irkens are scarfing down “meals” in the proper sense, because I’ve noticed that neither Zim nor his kin intrinsically understand the concept. When he’s trying to blend in as a human being, he puts a LOT of bizarre effort into convincing us that he, just like you inferior creatures, TOTALLY eats “food” on a regular basis like a normal person. When Irkens eat their own products, it’s all and only “snacks”. What follows is the conclusion that their eating habits are not structured into any schedule and that Irkens instead graze throughout the day as they please- and even possibly that eating altogether is more a recreation to them, instead of a necessary function to sustain life. Some fans have speculated that the PAK could provide an Irken with all of the necessary energy to survive absent of nutrition. I kind of want to contest this, given that caloric energy is only one purpose of taking in food… but it’s definitely the most immediate one. Nonetheless, they still eat constantly on screen and it all has to be going somewhere. Whether they need it or not, they still readily digest snacks (and presumably use those chemical building blocks to regenerate tissue damage) with a terrifying metabolic efficiency. Assuming that the resemblance of their snack foods and our leisure treats are not purely coincidental, one gathers that sweetness is the largest dimension of Irken cuisine. They are drawn most enthusiastically to carb-dense synthetic, plant, and possibly fungal matter in the same way that the human brain lights up at the prospect of fat and sugar-loaded meals. The flexible tongues of Irkens to me also resemble the nectar catching, segmented mouthparts of some bees. I would be willing to bet that they can taste salt, but jury’s out if it is something they crave, like us, or are repulsed by, like ants. That would have to come down to the scarcity (or not) of the resource on their home planet and whether or not desiccation was a serious threat in their natural history. In other regards, Zim shows strong negative reactions to most Earth foods, if not physically, than in his expressions. They definitely have powerful vulnerabilities to many human ingredients, and so are very sensitive to the presence of these toxins. I can’t imagine acidic or bitter substances are at all pleasant to them.

Now comes the much more interesting question I’ve thought way too long and hard about in the shower a time or two. Knowing that Irkens are likely a herbivorous breed, ergo, thankfully would have no interest in the consumption of the human race… what about the vise versa??? I don’t just want to know what they taste, but what would they taste like?

So, you’ve decided to mix it up for the thanksgiving dinner and forgo the same boring old bird for an Irken you have vanquished (via what I can only imagine was a freaking miracle of luck). What should you come to expect? Most importantly and I must emphasize this, the secret to preparing their meat is the same as Tolkien dwarves, you have to skin them before anything else. The separation of edible tissues from the cuticle is necessary to avoid ingesting the defensive toxins it contains. Even if the concentration is not enough to provide a danger to you, it could end up contributing an unpleasant, bitter flavor to the final product.

That done, discard the head and digestive organs. True as it may be that Irkens are wholly free of parasites, with a chance that the viscera could be edible, it’s not likely to taste that great and besides, do you really want to take chances with exposing yourself to an entirely foreign gut biome you have no immune adaptations to? And don’t even think about the brain- I don’t care how rare the infection rates are, alien prions are a big no. If you happen to run into any cybernetic implants during the cleaning, however, set them aside! They could be worth a small fortune in the right circles. But, for the purpose of eating we’re really concerned with the muscle tissues, a delicate white meat with a texture similar to fresh crab. The bones need not be wasted, and are fine to leave in, or can be boiled on their own to make a flavorful stock which can be added to soups or a delightful gravy. A surprisingly practical use of Irken bone could also be in the compost bin, being rich in chitosan and other powerful garden fertilizers. The flesh can do well fried, or roasted to a crispy exterior. The oven rule is the same as chicken, low and slow, to prevent drying out. Don’t be afraid to experiment with the gravy idea or marinades. The flavor profile of the meat itself would be utterly unique from what most of us are used to, comparable to a nutty crayfish. Savory, a bit of a sweetness, and a mineral hint that pairs quite well with mushrooms or rice.

I can’t recommend serving this to any guests with shellfish allergies in good conscience. If they insist, do so in caution and with knowledge of the risk of cross reactivity.

And there you have …. certainly a thing I did write and queue up for y’all!

Aberrant Fish

!! Hi there, if you are reading this, know that this post is currently going through a sort of overhaul and revisit as of September. With the release of the Iron Rig DLC, and me finally getting around to finishing it, several updates to the hyperlinks below are in the works to fix some outdated numbering and account for the MANY additional aberrations that the latest expansion has added to existing regions.

The first hint many an angler will get of the dark, insidious secrets these waters hold,

and yet, they are the first thing to be accepted as only another flavor of mundane.

The game text calls them grotesque. The fishmonger calls them corrupted. You get to call them a bonus. Rather than fear and revile them, tradesmen will pay a shiny extra penny to add them into their stock. They are gestured to and spoken of, but never truly elaborated on by the townsfolk. They have probably been here long before most of them, and so will be here long after they are gone. They were certainly here before you. Maybe you don’t need their answers, and yet if you are like me, you still witlessly question and keep dredging for more.

Like many things pulled from those cursed depths, they whisper flecks of madness from an impossible voice. What messages do they carry, and what forces do they play vessel to? Are they the lingering embers from a long-extinguished calamity, or are they harbingers of the next one to come?

I believe we have already seen signs of fire with our own eyes- impossible, great beasts that prowl the four (now five) coasts, the dying cult, gibbering fog…. That damned book. These tortured creatures are but another form of the same smoke.

To the question of where they came from, if your fisherman pokes around enough and braves the darkness, he may have already found a response in one of the many obelisks scattered around the map. Specifically, I refer to this.

This would suggest the aberrants themselves are what leaked in through the cracks that the largest of all monsters wants to rend apart? Not entirely, but in part. For the researcher at the Stellar Basin came to her own conclusion I want to factor in.

Her words give credence to the possibility that it is actually those greater beasts themselves at the heart of the corruption. I think she was half onto something, because what if these twisted forms, both large and small, were blooms along the same set of festering roots?

The more dark stones you disturb in the frenzy of your own madness, the more you learn about the age before your arrival, about the islands, and especially about their current guardians. The Mindsuckers- carrion puppet masters given a home, the Basin creature- a spore that miraculously survived its dive to the abyss, and the Serpent- lifeless stone made animate and malicious, all had their creation remembered in great detail by the obelisks. Some hints point that their emergence was rather recent, relative to even more powerful beings, such as the leviathan.

Maybe there are even more unseen horrors far below, blessedly out of our reach, for now. My view is that the malformed beasts are the aimless children of such unfathomable things waiting beyond the veil. With them came its influence, and its corruption, and from them it continues to spread to all life surrounding. The smaller rifts were always a transformative disease upon the harbor’s fish, but with the rise of the new monsters, the sickness runs farther and less avoidably than ever. Whether these aberrant spawn are a gift to the worthy, or another deceptive evil that leads to madness remains left to be seen.

I will be giving a spotlight to each of these fascinating specimens at the back of Dredge’s encyclopedia, including those found in the expansions, for further comment and appreciation. Updating the list below as we go along!

Every Dredge Aberration (2024), Part 2

Brood Squid

Encyclopedia #110

Aberrant form of Arrow Squid

Description:

Tentacles sprout from a glowing core inside a gelatinous sac. Other cores lay dormant alongside

Comment: The first aberrant I caught where the original being, if it ever truly lived, appeared lost entirely to the corruption. It has been hollowed out and made the bloated womb for a nameless invader. It invokes two visceral images in my mind’s eye. The first being an infected cell, swelling with viral load until it is bursted, spilling out with new capsules of infection waiting to start the cycle anew. The other is of those real squids in the world which brood their own eggs to hatching. They too, sacrifice the last of themselves entirely to bring their spawn into a hungry world.

How to catch: Another coastal spawner in The Marrows region, albeit only appearing after sunset. Can be gathered in trawl nets.

Snag Squid

Encyclopedia #111

Aberrant form of Arrow Squid

Description:

Tasting tongues writhe wildly around sets of yellowed, crooked teeth. The top row are flattened like human molars.

Comment: The first aberrant that made me recoil back in my chair with a grimaced “Euuh” sound when I saw it appear on my screen. To think of what caution such a thing must be handled with, lest the role of butcher’s hand and sustenance become reversed. The artwork makes horrible suggestion of one animal in a slow transformation to become many. This layered hunger promises terrible growth and sprawling if it is allowed to consume.

How to catch: Ditto

Barbed Eel

Encyclopedia #112

Aberrant form of Grey Eel

Description:

A spine broken with sharp angles and crooked curves. A row of teeth bent on revenge.

Comment: Fortunately for I, there exists frilled sharks with a more unnerving presence than this gnarled creature. It is much like the Marrows themselves, crooked and strange, but conquered easily. Hunger on, scoliotic elver, but you won’t be the one who feasts before the sun rises.

How to catch: This wretch and its kin will require an upgrade from the basic rod to bag. Fish during the day, around the shallow waters about The Marrows. I always found them mostly around the rocks. Can be trawl-netted with the appropriate equipment.

Host Eel

Encyclopedia #113

Aberrant form of Grey Eel

Description:

Numerous glowing shapes flicker and squirm behind a distended ribcage. The rest of the fish is withered and drained.

Comment: Could it be… another strain of what plagues the brood squid? Unlikely, but to the animal, the difference won’t matter- its fate mirrors the other all the same.

How to catch: ^Ditto

Cyclopean Flounder

Encyclopedia #114

Aberrant form of Gulf Flounder

Description:

A sprawling, jellied mass spills from a single eye socket. What appears to be a dark pupil is in fact the center of an egg.

Comment: Oh…. It’s a yolk. That’s the nucleus. Another life, traded for the potential of a new one. Neither encyclopedia nor the artwork help me address the question of whether or not this flounder carries a fertilized ovum, and frankly, I do not know which answer would unsettle me more. Mercifully, ironically, this change has blinded it.

How to catch: Active during the day, and dwells only in the shallow water of The Marrows. Can be trawl netted.

Riddled Flounder

Encyclopedia #115

Aberrant form of Gulf Flounder

Description:

Baggy skin perforated with countless cavities. A singular, shapeless mass spreads underneath.

Comment: Ah, I must wonder at this piece if the devs looked to the Surinam toad, and if they found such inspiration there that they created this. The semblance to one of the real world’s beautiful horrors is unmistakable.

If this were the intention, then the riddled flounder would be all the more foreboding a sight. While the flounder’s skin only shelters a single resident, the flat Surinam’s cavities are each protecting a tadpole. Something else that interests me about the grotesque flounder is that, like the other variant, this one has been rendered sightless. In place of its eyes are protruding siphons of a sort. Their function- unknown.

How to catch: ^Ditto

…..YEAH.

uhm..

i mean..

she did it 😃
