Banjo and Kazooie was always an odd pairing for me as Banjo became almost ornamental by the end of the game. Whenever I walked it was via kazooie because she was faster. Whenever I attacked I'd often resort to her stuff and her flying was invaluable as well. Banjo might as well have been the one in the backpack as far as I was concerned
Kazooie is a lazy bitch what can I say.
