I can think of several reasons why the name of this GZDoom WAD is appropriate. First and foremost, you will at some point enter a mandrill's ass. Seriously, it's an important plot point. Second, it's got some very colorful maps, for the most part breaking away from the stock Doom II resources we're intimately familiar with. It also has a humorous edge hiding behind the gameplay, with short dialogues and little sidepieces setting the tone, as well as some outlandish scenarios. Finally, as Aluqah points out himself near the beginning of MAP06, Mandrill Ass Project's acronym is MAP. Really, he couldn't have chosen a better name. Especially because of the part where you have to climb into a mandrill's ass.
