There is also a case that looks like a gun for the Wii Remote and Nunchuk. It is named the Zapper after a NES gun controller. When the Wii Remote and the Nunchuk are placed inside it, the shape of the controller in the player's hands is changed. The Zapper does not actually plug into the Wii Remote. It just holds it in place. The Zapper also includes a free, short game to help the player get used to it.
