Balance Stone

From the Super Mario Wiki

The Balance Stone is an important item in Wario Ware: Smooth Moves. It goes along with the Form Baton, just like the Wii Remote and the Nunchuk Attachment (the latter of which it parodies). It crashed on Orbulon's pink Oinker, flying near the Temple of Form. When Orbulon found it, it was right near the Form Baton, and the Temple of Form suddenly started to rise. This starts Orbulon's WarioWare: Smooth Moves game, Secret of the Balance Stone, which one must play with both the Wii Remote and Nunchuk in order to accomplish.
