Mimi

Mimi is a Mimic, a race of beings that are able to change their shape and appearance; disguising their bodies as inanimate objects (commonly a chest), in order to lure and capture prey. Mimics excrete an adhesive glue to hold fast to their prey or to hold fast to a specific surface (say a wall or roof) while waiting for prey or during travel. Alcohol will weaken said glue. She lives in a treasure chest, and any time it's closed she can completely change her appearance.
