Hell Box (ヘルボックス) is a low-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 one single target, it stretches its red head out of the treasure chest to bite. A Hell Box will also use Ranki Lei to confuse the party.
