One day some random lost carbonemys was walking around an ocean biome terrarium and suddenly noticed a strange plant covered in glowing purplish veins and black marks, it was hungry, so the carbonemys ate the plant

The next day it felt very strange, it also noticed that everything seemed to have shrunk, it wandered around and fell down a hole and found itself in the sea, it saw a school of pretty glowing fish and decided to eat them, that made it dizzy and it started to see rainbow lights, then it started seeing double and it's shell started to bubble, and it sprouted an extra set of legs, it had became the world's first megachelon,
