1. A reference to the Oddworld series of video games where one of the objectives is to free fellow members of the Mudokon race. The Mudokons are odd-looking, fairly slender and elongated, and gassy. To free them, one must chant to open a portal into which they jump.
2. To take a crap.
1. I've freed all the Mudokons on this level!
2. I really need to free the Mudokons!
