You're a regular dude using a public restroom.

Dungar, a repulsive poop monster, has been stalking you for your feces.

In the restroom, as you're about to leave, Dungar pleads from the toilet for your excrement, tempting you with an unspecified reward. (a single poop related wish )

Dungar: "Squish-squosh! Give me your poop! There'll be a craptastic prize, heh-heh!"
