Nunchuk
The Nunchuk is the first controller attachment Nintendo revealed for the Wii Remote at the 2005 Tokyo Game Show. It connects to the Wii Remote via a long cord, and its appearance while attached resembles the nunchaku. It features an analog stick similar to the one found on the Nintendo GameCube controller and two trigger buttons (a last minute modification changed the two triggers to one trigger and a "C" button, as described below). It works in tandem with the main controller in many games. Like the Wii Remote, the Nunchuk also provides accelerometer for three axis motion-sensing and tilting, but without a speaker, a rumble function, or a pointer function.
It has been confirmed that playing with the Nunchuk, when it is connected to a Wii Remote, is a controller method for Super Smash Bros. Brawl.
Oddly, while the Wii Remote can use the "-" button, the Wii Remote + Nunchuk cannot use it.
