Bell

The Bell is a musical instrument that appears in Link: The Faces of Evil and The Legend of Zelda: A Link Between Worlds.

Link: The Faces of Evil
The bell makes its debut in Link: The Faces of Evil, and is obtained when Goronu is defeated in his respective Face of Evil. When used, the Bell immobilizes all flying enemies for five seconds. It costs five Rubies per use.

A similar item, the Flute, can be obtained in Zelda: The Wand of Gamelon. It also freezes flying enemies.

The Legend of Zelda: A Link Between Worlds
In The Legend of Zelda: A Link Between Worlds, the bell is given to Link by Irene. When rung, Link can transport to any activated weathervane in the realm he's currently in.

 * In addition to flying enemies, the Link: The Faces of Evil bell can freeze the Fairies at Spearfish Falls.
