The Tree Huggers and Land Muggers art are promotional images for Munch's Oddysee, so it would naturally feature them.

I can understand your confusion. A lot of fans made the connection between the 'play as different sides' aspect and the 'Tree Huggers vs. Land Muggers' early promotional concept for Munch's Oddysee. This has been a frustration to me for years, because outwardly Oddworld Inhabitants never married the two.

In an early Dear Alf, Alf mentioned that Hand of Odd would feature 3 competing sides. In fact, I've seen designs that had 5.
