Killer Box

Killer Box (キラーボックス) is a mid-level Mimic-type monster in The World 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 single target, it stretches its white head out of the treasure chest to bite. A Killer Box will also use Ranki Lei to confuse the party.
