Grey Goo, also called Martian Goo in Tasty Planet Forever, is the titular character of the video game series Tasty Planet (with the exception of the third installment, Tasty Blue). He is a big blob of grey goo that starts out smaller than literal atoms, but soon grows to many times the size of the universe. He has a practically endless appetite and can eat anything smaller than himself.
He is shown to have a sadistic yet determined personality, as he stops at nothing to eat everything in the megaverse no matter how small he is at the start, although in doing so he does devour various different animals, plants, microbes, humans, planets, stars, galaxies, and literal universes, feeling no remorse at all no matter how much he eats.
In the original game, Grey Goo was designed as a bathroom cleaner, made to quickly eat dirt and other gunk to clean up restrooms. However, he can actually eat everything in his path that's smaller than himself. He bit the young scientist's finger, and then when the scientist washed his hands in the sink, he fell into the drain and was released into the wild.
Throughout the game, we see Grey Goo growing bigger and bigger and the attempts the scientists make to get rid of him fail, resulting in his size continuing to increase. After getting thrown into the water, he makes it back onto land, and then takes to the skies to eat everything there.
He proceeds to then enter space and eat the entire moon in one gulp, and then eats black holes, stars, entire galaxies, universes, and eventually grows so big that he eats the literal fabric of space-time, destroying the entire megaverse.ㅤ
Tasty Planet: Back for Seconds
In the second installment of the Tasty Planet series, Grey Goo is created by a malfunction of a time machine the old scientist created. Grey Goo is then fed candy, causing him to grow bigger and eat the old scientist's time machine. Grey Goo proceeds to be transported to 65 million years ago right before the dinosaurs went extinct. Grey Goo then eats the Chicxulub asteroid right before it hit earth, causing dinosaurs to appear in the present due to having never gone extinct.
After that, he travels to ancient Egypt and grows big enough to eat the pyramids of Giza, causing them to disappear from the present, and then travels to ancient Rome and eats the entire city, forcing them to unite and rebuild the civilization therefore preventing the fall of the Roman empire.
Luckily, every time the Grey Goo jumps time periods, his size resets, preventing it from growing big enough to eat the world. The old scientist predicts that its next time jump will be its last, which it is, but he ends up transporting to the future where he eats planets, stars, galaxies, the very fabric of space-time (again), and then finally the Turtles of Time, peaceful entities that hold the universe on their backs, destroying the entire megaverse and leaving a simple white void.
Additionally, an Adobe Flash version of the game called Tasty Planet Dinotime, which is basically just the Laboratory and Late Cretaceous levels, has an alternate ending. In it, Grey Goo grows large enough to eat the earth, and due to that humanity never existed. However, if humanity never existed, that means Grey Goo was never created. And if Grey Goo was never created, that means that paradoxically, the world was never eaten, leading to a vicious cycle occurring over and over and over again.
Tasty Planet Forever
In the fourth installment of the series, Grey Goo (known as Martian Goo in this game) lives inside of a drop of water and is so small that he's the size of quarks (which you eat at the start). (Which Should not even be possible) This game takes place in the future, where humans have now inhabited planet Mars. Martian Goo starts off by eating quarks, then moves to nuclei, then atoms, and then molecules.
He grows larger and larger, eating microbes, water drops, crumbs, space snacks, robot dogs, buildings, mountains, craters (somehow) and then the entire planet of Mars, followed by the rest of the solar system. He grows even larger and eats stars, weird manta ray creatures, and then the entire galaxy. He then eats galaxy clusters, a Flying Spaghetti Monster, and then grows big enough to eat entire universes that look the same as the quarks at the beginning of the game, meaning the end truly is the beginning.
Why He Ate His Way Into Our Hearts
- His design is adorable and super huggable, and makes you just want to snuggle him (although that would get a bit sticky).
- His design improved massively in Tasty Planet: Back for Seconds, making him look much cuter and more snuggly.
- He also has an alternate skin that takes the form of a black hole, which is pretty cool, but since it's an alternate skin and not an entirely different character it still has the same voice acting as Grey Goo, which is pretty hilarious as it's really silly to see a black hole saying "Yum yum!"
- His shade of grey is a really aesthetically pleasing one.
- Unlike most other characters in Tasty Planet Forever, it makes sense as to why he grows when he eats, as he's a pile of goo that absorbs the matter he ate into himself.
- His endless appetite is hilarious, as he literally starts out eating quarks and then eventually grows large enough to eat the very fabric of space-time.
- His design, while simple, lives up to his name and is pleasant to look at.
- His size is shown in-game, meaning it could be a good way to make people more aware of obscure measurement units such as zeptometers, attometers, femtometers and picometers.
- His voice is adorable as well.
- When he completes a level, he shouts out a cute "Woopah!" which is super endearing.
- He occasionally says cute little lines like "Yummy" when he eats.
- He saved the lives of millions of dinosaurs, albeit accidentally.
- He sometimes gobbles things up without even realizing it, which is really endearing.
- When he eats something, his color temporarily changes to the primary color of that thing, which is pretty creative.
- When he eats multiple things at once, his color changes to a mix of the colors of those things, which can look pretty cool.
- His ability to eat things that are literally the absence of things (such as craters) is incredibly funny, albeit nonsensical.
- He is a creative parody of the grey goo scenario, a scenario where autonomous self-replicating machines create more and more of themselves and eventually take over the world.
- What makes this even better is that he isn't just a carbon copy of this scenario, as he is just one entity that instead of creating more of himself, replicates his cells to allow him to grow bigger and bigger the more stuff he consumes.
- He is somehow able to fly without wings, swim without dissolving/melting, and travel through space without needing air, which is pretty impressive.
- Even when he grows to the size of multiple gigaparsecs, he still has his same adorable voice, which is both hilarious and cute.
- He was able to escape from the idiotic scientists containing him hilariously easily.
- Although he has a number of unlikable things about him (see "Bad Qualities"), a number of them are fairly hilarious.
- He ate several Space Manta Rays, presumable saving various different galaxies from being eaten by them.
- He also ate a giant Flying Spaghetti Monster (or as the game calls it, a Noodly Monster), presumably saving several galaxy clusters from being devoured by it.
- His original Tasty Planet title screen is very well designed, and he looks very awesome and menacing on it but still adorable at the same time.
- The whole paradox that occurred in Tasty Planet Dinotime was really hilarious and ironic, as him eating the Earth while in the past caused an endless time paradox/loop.
- He managed to prevent the fall of ancient Rome, albeit by destroying the entirety of ancient Rome first.
- He once cleaned all of the cyanide out of a bunch of water, presumably saving multiple lives.
- Depending on how you look at it, he could be either the protagonist or the antagonist of the series.
- His strange abilities, while funny, are unexplained and nonsensical.
- He did eat one of the seven wonders of the world while in ancient Egypt.
- He bit the young scientists finger before he even knew him, which even though he deserved it was kind of rude of him.
- His backstory in Tasty Planet Forever is pretty uncreative, as he's simply some organism living inside a water droplet, with no explanation as to why he's there.
- Additionally, he devoured multiple planets, humans, buildings, galaxies, universes and enormous turtles, which, while funny, is also super destructive.
- His endless appetite can be kind of annoying to some people.
- Sometimes he's kind of mean and eats things just for the sake of eating them.
- He's kind of stupid and oblivious, and he's often blinded by his voracious appetite that just makes him want to eat everything he sees.
- Depending on how you look at it, his eyes can look kind of soulless.
- While he is a nice shade of grey, grey isn't the most pleasant color out there.
- He's pretty inconsistent, as sometimes he's doing good things for humanity/the universe, but other times he's just devouring everything.
- His design was way less appealing in the original Tasty Planet, with him looking way more dead-eyed and his body looking like a splattered paintball.
- Technically speaking, he did destroy the entire universe and beyond...
- The only installment in the Tasty Planet series that doesn't feature Grey Goo is Tasty Blue, which instead features a shark as its main character.
- When Grey Goo changed the past causing things to change in the present, everyone seemed to be aware of the changes, which doesn't make much sense considering that rewriting history would also rewrite people's experiences and memories too.
- In Tasty Planet Forever, Grey Goo starts out smaller than atoms, which isn't even physically possible.
- In fact, he starts out almost being smaller than quarks, the smallest known objects in the universe.
- Grey Goo is the only characters in Tasty Planet Forever to have a starting size smaller than a millimeter.
- Grey Goo also starts out smaller than a micrometer, a nanometer, a picometer, a femtometer, and an attometer. The only units in the metric system that Grey Goo doesn't start smaller than are zeptometers and yoctometers (also Planck length if you count that as a valid unit of measurement).
- In Grey Goo's Tasty Planet Forever cutscene, he is shown to be much larger than he actually is when you start the level.
- Despite being the main character of the first two installments in the series, Grey Goo is only featured in the final world of Tasty Planet Forever.
