Imohmushii

Imohmushii (lit. Sweet Potato Insect) was a caterpillar that Escargoon found in King Dedede's castle garden as a demonstration for his Insta-Monster-Mixture formula that he had created in the episode "The Empty Nest Mess". The caterpillar was injected with Escargoon's serum and eventually grew and transformed into a huge monster mutant that squashed the King and his servant snail, and afterwards picked Escargoon up and swung him around with his jaws. It was here that Dedede was happy to know that the invention worked and now he could make all the monsters he wanted without having to pay Nightmare Enterprises a cent. Whatever happened to Imohmushii after his small appearance in the beginning of the episode is unknown.

Physical Appearance
Imohmushii starts out as a small purple caterpillar with greenish gray legs, round eyes, and a green head with a yellow mouth. When mutated by Escargoon's formula, he grows to giant size and gains silver jaws, glaring blue eyes, and yellow spikes running down his back in the process.
