Do! Run Run, known as Super Pierrot in Japan, is the fourth and final incarnation of Mr. Do!, the Universal video game mascot. Returning to his Mr. Do! roots, the clown has a bouncing powerball with which to hurl at monsters. What makes this game novel is that instead of burrowing through the ground to get at cherries, Mr. Do runs along the playfield picking up dots, and leaving a line behind him, which the player is encouraged to create closed off sections with, which turn any dots left behind into cherries.
