Dive

Diving is a move that allows Banjo and Kazooie to swim underwater.

Banjo-Kazooie
In Banjo-Kazooie, the Dive move is learned in Spiral Mountain. It is performed by pressing while above the water.

Banjo-Tooie
In Banjo-Tooie, the Dive returns and is performed the same way. While Split-Up, Banjo can dive by himself, unlike Kazooie who fails when attempting to do so.

Banjo-Kazooie: Grunty's Revenge
In Banjo-Kazooie: Grunty's Revenge, Bozzeye teaches Banjo how to Dive for 25 Musical Notes in Cliff Farm. Unlike in previous entries, he can only dive in certain spots indicated by bubbles coming out of them.
