Sweet! Other than Tony DiTerlizzi's interpretation of the Kuo-Toa (which made them really look fishy), this is my favorite incarnation of them yet! Yes, yes, yes!
Overall, I'm very pleased with the new look of monsters in general. I did not like the 3rd Edition version of monsters at all. I mean...AT. ALL. For me, the 3rd Edition monsters looked all Cthulhu-ed out and stuff. The displacer beast looked like it was from Venus, and the Choker looked like it walked out of the pages of CoC.
Loving it.
