Egg Firing became much more advanced in Banjo-Tooie, with the introduction of the Egg Aim ability, Airborne Egg Aiming , and Talon Torpedo moves. Egg Firing was removed in Banjo-Kazooie: Nuts & Bolts due to Banjo and Kazooie forgetting their moves, however, there are many vehicle parts which enable you to fire eggs. In this situation, you need an Ammo storage part and the proper firing setup as well.
