Enhance your New Super Mario Bros. Wii experience with the new B.O.S.S. Controller from Performance Designed Products (PDP), a top gaming accessory provider. With a suggested retail price of only $9.99, the controller makes a great stocking stuffer.
The B.O.S.S. Controller, which stands for Big Oversized Super Shell, is a plastic grip that clips securely on top of a Wii remote. It features enlarged action buttons and an enlarged D-pad that are activated by pass-through mechanisms.

The controller provides a better ergonomic shape when the Wii remote is being used as a classic controller, and retains that "classic feel" that ties into the nostalgia of Super Mario Bros. The controller is perfect for the upcoming "New Super Mario Bros. Wii," "Super Mario Kart Wii" and "Punch Out Wii," as well as all Nintendo virtual console games. It is available in four Super Mario Bros.-themed colors (red, green, blue and yellow) to help support four-player co-op play.

It looks kind of shoddy in that image but reminds us of the retro controller so it could be useful.
