What I'm trying to say is that the creature is odd enough to be an Oddworld creature - ignore de dog costume and the teddy - Is that so hard to understand?

Okay, it's an odd looking creature. But Oddworld characters are designed with a specific purpose in mind. There is no reason why an Oddworld designer would draw an Oddworld creature wearing a Planet Earth dog costume and chewing a Planet Earth stuffed toy.

And even if there were some ineffable reason why he would do that, he wouldn't be allowed to display the image publically, or offer it for sale.

Because he wants us to think that this creature is not going to appear in any new games!
I'm not saying that it will appear, but we never know until the games come out, right?!

I heard that the Choupug rides a Unicorn in the new game.

CAN'T DISPROVE IT!

Yeh did you see his darth maul chibi picture as well? Maybe that's going into Oddworld, maybe there doing a merger with lucas arts...oddwars? No.
