Beak Bomb

Beak Bomb is an aerial attack learned in Freezeezy Peak. If is pressed while flying, Banjo and Kazooie will hurl themselves at a target like a missile at the cost of one Red Feather. This ability is the only attack capable of defeating Sir Slush, and while it is the most damaging of all attacks aside from the Wonderwing, it can be extremely hard to aim, especially when trying to hit a moving target; as such, its main purpose aside from Sir Slushes is hitting switches or targets which are too high for other abilities to reach.

In Banjo-Tooie, can be held to keep the Beak Bomb going for an additional feather every second. Tilting the control stick also gives the attack limited directionality in mid-air, making course corrections easier if you realize you're about to miss a target (or hit something undesirable). Because of its ability to gain altitude in this way, not to mention the huge horizontal distance it can cover, the Beak Bomb is an excellent way to fly across long distances quickly at a minimal feather cost, considering the steady loss of altitude which accompanies flying normally.

One should use this move cautiously, however, for should the pair hit anything which was not intended to be struck with the Beak Bomb, they will suffer injuries and may be forced to land from the sudden drop in altitude if used too close to the ground. Beak Bombing the ground also results in a long period of lag as the two slide a fair distance. On a side note, the Beak Bomb has its own death animation if Banjo gets killed from Beak Bombing the ground.
