The Giant Red Feather is an item in Banjo-Kazooie. It is located in the very last room before the final fight with Gruntilda in Gruntilda's Lair. It replenishes all of Banjo and Kazooie's Red Feathers. Banjo and Kazooie must pass a Note Door that requires 846 notes to unlock in order to reach it. It isn't required for the final battle, but due to Grunty having to go aerial during the battle, it is an immense help as it allows the player to easily recharge on red feathers before the battle.
