Mimic

A monster that hides in a treasure chest, it appears to be a part of the undead family. Their body is composed of the chest and their digestive juices contained inside. When an adventurer opens the chest, the Mimic will drag them inside and close the lid, bathing them in digestive juices.

A very timid monster, it spends almost it's entire life shut inside the box but once she catches her prey, her attitude completely changes as she enjoys dominating them. Dragging her prey inside of her, she enjoys watching their despair as they are slowly eaten. Moreover, Mimics will be sure to cover the male's genitals with her digestive juices first, cruelly watching their reactions. A man captured by a Mimic can only look forward to a disgraceful, miserable death.

There have been cases where the Mimic really enjoys the reactions of her catch and chooses to instead torment them for the rest of their life, or until they become bored. When this occurs, they will then eat their prey.
