Mimic

Mimic (ミミック) is a low-level monster in The World with type of the same name that disguises itself as a treasure chest, often lying rigid on the ground. From time to time, or when it sees one or more PCs, it will stand up with six crab-like legs. To attack a target, it stretches its yellow head out of the treasure chest to bite. A Mimic will also use Ranki Lei to confuse the party.
