FunHouse’s primary feature is the talking head of a ventriloquist dummy, named Rudy, located in the top right corner of the playfield. Rudy responds to events in the game, including informing the player of special bonuses, taunting and heckling the player, and appearing to follow the ball with his eyes. The player must put him to sleep by advancing the FunHouse’s clock to midnight, and uncover the surprises awaiting inside the trapdoor. The technology behind Rudy’s facial movements was dubbed “Pin-Mation” by Williams.
