Wonderwing

Wonderwing is an ability is learned from Bottles in Clanker's Cavern and can be executed by holding and pressing. While Wonderwing is active, Kazooie will shield Banjo with her wings, making the pair invulnerable to harm at the expense of one Golden Feather every two seconds. Most enemies will die instantly when touched by the Wonderwing shield, making it effective in quickly dispatching stronger foes like Snacker and making it the only move capable of killing certain enemies like Tee-hees, Mum-mums, and bees. This ability can also be used to cross dangerous terrain such as superheated sand or bramble, but cannot be used to absorb damage from long falls.

In Banjo-Tooie, most enemies will flee at the sight of the Wonderwing, sometimes forcing the player to chase them down just to hit them. Wonderwing will protect Banjo and Kazooie from being crushed by various hazards, but only when together, since neither of them can use the ability on their own. While the move was required for various parts of Banjo-Kazooie, Banjo-Tooie only has one place where the move must be used: the superheated waterfall in Hailfire Peaks.
