That greedy guy, Plunderin' Pete, has snatched the legendary Crystal Mickey statue from the Clubhouse. What's worse, without the magic of the Crystal Mickey, the Clubhouse starts to sink into the ground, never to be seen again. The pals have to get that statue back, and a nail-biting, high-stakes adventure like this requires an extraordinary hero to lead the way, namely, Kansas City Mickey. With Kansas City Mickey in charge, not even Plunderin' Pete's trickiest traps can stop us recovering the Crystal Mickey and getting it back in time to save the Clubhouse.
