Kamaro

Kamaro is a ghost that appears in Majora's Mask. In life, he was a dancer, but he is now filled with regret due to him not being able to pass on his dance moves to the world while he was alive. He planned to bring the world together with his choreography, but he inexplicably passed away and now lingers the world wishing he had taught his routine to someone.

The ghost dancer can be found from midnight until 6 AM in the giant mushroom-shaped stones near the entrance to Snowhead. When Link eases his soul, his dancing ability becomes encased in the Kamaro Mask, granting it to the young hero and trusting him to make his routine into a "popular dance craze." With this, Kamaro's dance can be taught to the Rosa Sisters in West Clock Town to gain a Piece of Heart.

Trivia

 * His theme can be heard in West Clock Town at night even if Link hasn't taught the Rosa Sisters his dance.
 * His theme is also similar to Majora's Mask's theme.
