Day 20 - Favorite Monster (Humanoid/Natural/Fey)
The Displacer Beast (I'm not up on monster categories, but the the 4e Monster Manual assures me is that the Displacer Beast is of Fey origin). I've always liked creatures with tentacles, and I love any sort of cat. Though as cool as these creatures are, I do hate fighting them.
