This might sound like a weird question but hear me out: the grey goo seems to be very good at multitasking, it is canonically self replicating nanotechnology, meaning it is not one single body as one single entity, it is thousands or millions (depending on its size) of small things controlled by a single conscience in a hyper coordinated manner, this is also further reinforced by the fact that in the menu screen of the original game, the grey goo seems to take advantage of its amorphous body to catch more objects to absorb, extending certain parts of itself in a way that was clearly intentionally done by the goo, it also seems to do this several times at the same time in that screen, meaning that every bit of the grey goo is effectively a hand that it can use, implying that it is very good at paying attention and being coordinated. Another thing is that it has been able to eat time, not a cosmic manifestation of it, just straight up time, as a concept, I believe that once the grey goo eats its universe, and therefore time itself, it effectively ascends into a state of existence where it can view the past, present and future simultaneously, whenever it wants, so it can look inside the history of a certain universe and be able to experience its entire history or future in a few seconds. The other feasters wich to me are implied to have kept growing and consumed their universe (see my previous post in my account for more info) would have probably not been able to use this, as that would give so much raw information it would shatter their mind, However, other characters using its self replicating nanotechnology would probably be able to use it as well, considering that again, it is nanotechnology, it implies that characters like Mippy, Nano shark, and the Parisian cat, would also have that same hyper coordination the grey goo uses, meaning they can also take in cosmic amounts of raw info and be able to use their abilities to view the past, present and future once ascending their universe.

here’s what I personally think:

For the original grey goo, it is clearly shown to die after eating the universe

the One in back for seconds definitely did as it ends in the infinite stack of turtles of time, wich the goo clearly started to eat.

goldy and smiles were killed by nanoshark

nanoshark probably did keep growing to the point it fully destroyed the universe and probably went on to consume other universes, as we see that the Kill switch failed and that the nanoshark seems to take pride in its newfound size, judging by the smile it makes at its final comic panel, and is also seen eating the other planets, so overal, I’d say it willingly kept on growing.

The Parisian cat was told to eat everything and it clearly took that literally, so it will definitely destroy its universe and other Universes

the octopus definitely kept growing, but probably wouldn’t try to eat the cosmos and the earth, as that would contradict its whole motivation of ridding earth off its polution, it wants to save it, not eat it, and this seems the same for the penguin.

the rat does not seem to have any motivation for its consumption other than what appears to be an insatiable appetite, judging by this, it probably ate its own universe and would be willing to eat other universes in the process, its lines are that of the grey goo but sped up and at a higher pitch, meaning that they are technically their own voicelines and by that logic, they are clear expressions of joy through eating and growing.

the dingo also seems to enjoy the act of eating and growing, as it makes playful barking sounds whenever the player eats or reaches the target size, it also demonstrates defiance against its creators, implying it possesses free will, and judging by the shared universe rule that seems to be in play for all the characters, it does not need to breathe, meaning it can survive the vacuum of space, by that logic, it would definitely keep growing to the point of consuming its own universe, and would start eating the multiverse as well (might as well add that this is only assuming the multiverse does in fact exist in the tasty planet universe)

the basking sharks whole motivation involves revenge against humanity, and the outcome of the final level does not seem to satisfy that goal, it would probably consume the earth to achieve its goal of eradicating humanity, and the thing is, you might think it would stop there, but then it would be Forced to bear the extreme loneliness that would come with it being the last of its kind, it also seems to actively enjoy eating and growing, signified by joyful “gurgling”(this was the best description I could think of) sounds implies that it does derive joy from these acts, meaning that it could have used that joy as a coping mechanism, wich would snowball to it also consuming its universe, and other universes as well.

the bee probably consumed its universe and also would have come to feast on the multiverse, we literally witness it surviving the vacuum of space, and it yet again seems to derive joy from eating and growing, signified by its buzzing voicelines.

martian goo definitely kept growing as it is implied that its final level is an endless loop.

You might think that mippy’s feat of converting everything into paperclips as something that disproves the existence of a tasty planet multiverse where the characters are all contained, however, its final comic panel never says everything was made into paperclips, it says everything in its UNIVERSE was made to paperclips, implying that it might‘ve converted other universes into paperclips as well, this is reinforced by the fact that the command was to MAXIMIZE paperclips, meaning that there is no true limit as to how much it can convert.

When it comes to Cetus, you might think that he would have been stopped by the gods, but looking at how the gods seem to have responded to Atlantis’ transformation from fair and kind to prideful and greedy, I think they have less agency over the world than it seems, we see the older god request the younger god to teach the Atlanteans a lesson in humility, when the older god, wich is a literal god, could probably have done it just fine as well, another thing is how we see the younger god respond to Cetus consuming Atlantis, instead of directly intervening, he seems to scold Cetus from the clouds above, and at its first comic panel, we see the younger god direct A lightning bolt over cetus, as if blessing him with its power of growth and consumption, if the younger god is capable of doing this, then he should be able to intervene in Cetus’ consumption rather than scold him at the clouds and hope it works, this implies that the Gods of this universe exist as passive conductors rather than active leaders, this could also be a moral constraint they have placed on themselves, as we do also see the older god asking if he lectured the atlanteans, implying the older god wanted peaceful teaching rather than orchestrating disorder as a means of teaching a lesson in humility. This lack of agency paired with the joyful “groaning“(I could not find a better description for this) that happens when you complete a level or eat something would imply that it probably grew to consume its universe and moved on to the multiverse.

You might think the house hippo stopped growing after the world ran out of maple syrup, but I think It was able to consume its own universe and went out into the multiverse, the first reason is because of the fact that we see it consume things other than maple syrup, And the App Store description of it says that it consuming maple syrup triggered a “runaway metabolic response“ implying that the maple syrup was an ultimate catalyst Rather than something the house hippo’s diet is strictly restricted to, this evidence along with the fact that it seems to enjoy eating and growing, signified by the joyful snorting sounds it makes when it eats or reaches the target size is evidence that it had indeed been able to consume its universe.

The UFO definitely kept growing, we see that the aliens responded to its uncontrollable growth with laser defenses, if they had something like a kill switch for it, they would have used it as the first response against it.

the baby dragon also definitely kept growing, it seems to Derive joy from eating and growing, signified by the sounds it makes when it eats, and also demonstrating a tone separate to the tone when it eats when it takes damage, and we see it looking for more food in its final comic panel, it seems to be driven by an insatiable appetite similar to the rat and as a result, it likely got to consume its universe and would continue in eating the multiverse.

Clay goo definitely did not keep growing as it got killed by James Sayer.
