The Great Circus Mystery Starring Mickey & Minnie (released in Japan as Mickey to Minnie: Magical Adventure 2 - The Great Circus Mystery, the former sub-title translating to "Mickey and Minnie") is a side-scrolling platformer developed and published by Capcom for the Super Nintendo Entertainment System and Sega Genesis in late 1994.
The sequel to Magical Quest Starring Mickey Mouse, Great Circus Mystery follows Disney mascots Mickey Mouse and Minnie Mouse as their fun-filled day at the circus is ruined. While looking for their friend Donald Duck and dog Pluto, they learn from the Lonesome Ghosts that the Evil Baron Pete and his weasel henchmen are causing chaos throughout the land, and must set out to stop them.
As with the previous game, players in The Great Circus Mystery can utilize special magical costumes that grant them special abilities. It is the first game in the series to feature two-player co-operative gameplay (with one player as Mickey and the other as Minnie).
The game was later ported to the Game Boy Advance in 2003 as Disney's Magical Quest 2 Starring Mickey and Minnie (which was released in Japan as Disney's Mickey to Minnie no Magical Quest 2, loosely translated to "Disney's Magical Quest 2 of Mickey and Minnie"). Multiplayer connectivity is supported with the system's link cable.
