Harley Quinn uses a laughing gas to knock out the staff of Arkham Asylum, and all the villains escape. By taking on a series of puzzle-based mini-games Batman and Robin must locate them and bring them in once again. The activity center is based on the Adventures of Batman and Robin seasons that were actually the later part of Batman: The Animated Series (1992). The mini-games are located in the game's three main areas - the Batcave, Wayne's Manor and the streets of Gotham City. These mini-games include a paint-by-numbers game, a connect-the-dots game, decoding (a clone of the Hangman game), Robin mixing up an antidote for the laughing gas, the Towers of Gotham (based on the classic Tower of Hanoi peg game), the subterranean sewer mazes, simple jigsaw puzzles that depict scenes from the show, the Joker's memory match game with cards and Two-Face's special matching game based around fake jewelry.
