Memory:Greater mimic

You haven't known fear until you've been starving, spied a ration of food on the other side of the room, hovered over your salvation, and had this HUGE tentacle emerge from the thing and smack you upside the head, locking your muscles with some sort of toxin. All you can do is sit and watch as the food grows teeth and tries to eat YOU. Sure, you might survive, but you'll never trust another free meal again, and that's not the worst of it... The worst part is that these creatures can look like ANYTHING -- a potion, a scroll, armor, ANYTHING, and the greater mimics are so good at it you might never know what hit you. A really nasty sort of creatures, these beasts disguise as items harmlessly lying on the floor. But if you try to slip your feet into those boots, the boots will grow teeth around the rim and try to gnaw your feet off. Fortunately, they often drop their guise while you're still some way away, so at least you won't be taken completely by surprise.
