Mimics

The careful adventurer should be always alarmed if there are lots of bones around a chest. Because some chests like to bite. These are Mimics! Mimics; treasure chests with very sharp and hungry teeth wait for a careless hero trying to loot them, then attempt to bite off a limb or shoot poison at them. However, should they miss their prey, they are exposed, and are then easy to kill.

Mimics are only found in dungeons.

Mimics appeared in Ultima I, IV, V, VI and IX. However, in Ultima IX, Mimics are quite different, growing arms and legs when touched, and attacked the Avatar with its claws.
