My favorites creatures are the Mudokons, Glukkons, and the Vykkers. Most of my reasons are the same as what other people have said. The design for the Vykkers is great, and their personalities are great. The Glukkons, as the evil businessmen, in suits, and I think its so cool how they have to hop around, and have the sligs do all their dirty work for them.
I really like almost all the Oddworld creatures, and I have many more reasons that I dont need to bore you with.
