Some players have found that when they start the Spin Attack tutorial in Disney Epic Mickey, Mickey continuously performs the spin attack move despite the Wii remote not being shaken. Players report that this happens even after they've relaunched the game or shut down and restarted the Wii system.
This issue may be caused by the internal sensor in the Wii remote being jammed or stuck.
To prevent this from happening, hold the Wii remote in one hand with the button side down. Firmly, but not forcefully, tap the button side of the remote against the palm of your other hand a few times.
