All signs point to you only having to wait 5 months to find out what a Western set on Oddworld would be like. It's not difficult to picture what sort of creatures there would be, since we've seen a plethora of potentially includable new characters on the X-Factor show. You can see screenshots on
Atusi's brilliant page or
Hayley's equally brilliant Steef page. Notice the chicken hillbillies, hunter, warthog and salamanders. I've attached an image of the toad blob.
