If you look at
www.oddworld.com and go to the oddworld universe section and click on wild life you will get a list of all the creatures we saw plus you will get a concept drawing of a meech which I think is very cool looking and you will get picture of a rat anouther creature we will see in Munch and something else that I don't know will be in the game but it lookes cool. It is a Sea Rex. I think it might be in the game possibly M.E.
