The player who accidentaly became the Ultimate Croaker is Maid of Space and they are the ultimate fairy metamorphosis - instead of frog being turned into fair maiden by a kiss of a prince, a maid is turned into frog and they are still the most beautiful creature. Of course the prince was kissing their cold corpse to revive their soul into their dream image, after they were killed as result of wicked Witch's machinations who was merely saving them all from impeding doom of failing the session.
This is the god damn level of symbology and references Homestuck itself has and you need to make this into a Fanadventure ASAP. Curiously enough, our Maid of Time also has a Frog Metamorphosis, but rather than the last step, it’s her fist one, so… Frog > Robot > God Tier, maybe the Maid of Space inverts this going God Tier > Robot > Frog?
