Plump was created for Eat Yourself, a mobile game about a self-cannibalistic flying pig named Pinky. The letters were designed to resemble Pinky's flesh, with a tasty candy coating. The star-shaped counters are perfect reproductions of Pinky's belly button and butthole (both of which factor largely into the game's narrative). On screen, the individual characters jiggle up and down dynamically, based on a special algorithm, and are responsive to touch.
