ShellNumemon is a Crustacean Digimon formed when a Numemon is smart enough to search out a shell to protect itself. This makes it slightly more intelligent than Numemon, but it’s also highly skittish and will hide inside its shell at the least provocation. While in its shell its defense is extremely high, allowing it to withstand being kicked or stepped on. Its special moves are Shell’s Attack, by which it bashes opponents with its shell while hiding inside, and Mature Poop, by which it throws gobs of poop that have accumulated in its shell.
