Skyrim
It's easy to summarize a Mimic: they disguise themselves as chests, waiting for victims to try to open them. When a wretch tries to do so, the Mimic will attack the victim with its long sharp claws and try to bite the poor soul with a large mouth full of sharp teeth, a bite so powerful that it is often described as causing instant death.
