What the **** is this? Some kind of emaciated platypus? How the hell is this threatening? Oh wait, it isn't really native to out plain, ok makes sense, looking like that. Ah and it's completely invisible, again, looking like that it's probably for the best. I wonder how it attacks...

By latching onto a victin without it knowing, and over some time slowly draining the victim of all thought until there's nothing left but a brainless husk. Oh...

The Thought Eater is awesome.
