Honestly, i don't like them their design, I mean, the idea it's great, but not the best =/, Anyway, The aspect of "Mon" has some sense, 'cause he can transform his body to look diferent and cheat to others... and looks like that because he spended all his budget of his design, tha's why he looks awful xD Ah, and Blurp has that name for the onomatopoeia of "Burp"... and he ate his own legs :P (and the holes in his bodie are like a nose and also like something that can flee smells, like some insects, or that plants than eat flies)
