(bby)The least intelligent adversary, since it's moss. I think I'm the only one who finds the name of this and the following one to be extremly clever.

Both players and monsters can freely walk on Mucho Moss, the only difference being the player finds it unpleasantly tingly.
Occasionaly spreads to surrounding four tiles. Name is Spanish for "Much Moss".
