You must not have studied the oddworld creatures enough.
Those exact same suggestions have been made before by
other people. I still think scrabs have to many simularities
to crabs.
I don't know if you noticed all the thing Abe
can do in the game. He can jump to a ledge and climb
up very fast. And thank to his claws he can climb walls
pretty easy and jump long distances down. As can any
other mudokon. The best earth-like animal to compare him
to is a lizard. So lizard humanoid maybe.
Let me guess, you said paramites are pigs did you. Well that
because the sounded almost like one in games like MO.
They don't even look like one. End of story.
Vykkers are just maybe two steps ahead of us in the world of
abusement to living creatures. And glukkons are a little more
than just bosses. They're masters in the corporate world.
Visit the Oddworld website or do some research online or
