The pad features eight buttons: the directional inputs, the 
and 
buttons next to the up button, and the 
and 
buttons on the top corners of the pad. In the center is a light-blue silhouette of Mario, specifically the Super Mario 64 artwork of him performing a Sweep Kick, but made to appear as if he is breakdancing.
