Wonderwing

The 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 undead enemies and bees. This ability can also be used to cross dangerous terrain such as superheated sand or bramble, as well as absorbing 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. Wonderwinging 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 (there's no explanation as to why Kazooie can't use it on her 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. The overall combination of less intended uses, the increased difficulty of using it to attack, the fact that enemies respawn quickly anyway, being unable to use the move while split up, and its uselessness in toxic gas and boss fights makes the move far less useful.

In Banjo-Kazooie: Grunty's Revenge, the Wonderwing can only be activated by pressing while standing on a Wonderwing Pad, and cannot be used at any other time.
