OK this is a new character, I mentioned it to and he whipped up the image in the bottom left instantly, cause he's a boss.

So he used to be a normal kangaroo, then was captured by a monster in the Citadel and turned into a sort of monster version of himself. He has two ways of trapping you, stuffing you in his slime oozing pouch, or his tail splits open into a big maw, they both lead to the same holding chamber or belly, which drains you of your energy. He's not a true bad guy, he just has a hunger he can't control, so he's a "on again, off again" ally. also his hair is sorta jelly :O and he has suckers on the underside of his tail and can squeeze constrict drain things with it :3 He'll be changing over time, just introducing him. Thank Samael for the awesome input and name :3
