Egg Firing is a generic move that appears in Banjo-Kazooie, Banjo-Tooie, and Banjo-Kazooie: Grunty's Revenge. It consists of Kazooie firing Blue Eggs from either her mouth or butt (along with a fart sound effect). In Banjo-Kazooie and Grunty's Revenge, you can only fire eggs from your mouth or butt. However, Egg Firing became much more advanced in Banjo-Tooie with the introduction of several new types of Eggs, the ability for Egg Aiming, the Breegull Blaster, Airborne Egg Aiming, and Sub-Aqua Egg Aiming moves.
