Mysterious Treasure Chest

You pad up to the mysterious treasure chest. It's perfect: solid wood, iron bands, no lock. You lift the lid, but you don't see any treasure. In fact, you see a horrible writhing mass of flesh and eyes and teeth! Oh shit, why is there a mimic in the bathroom!? You're doomed!

Your thoughts are interrupted by a half-dozen tentacles rising out of the fleshy mass. Tentacles? Maybe you aren't doomed! Maybe it's one of those sexy mimics. The tentacles grab you - and pull you straight into the mimic's waiting mouth. Looks like it is not a sexy mimic. Damn. You die!
