the use for the eggs and key was intended to be the stop 'n' swop feature, where you had to take Banjo Kazooie out of the n64 and then put Tooie in and the data of the eggs/key would transfer over somehow and unlock features. But nintendo made a decision with the n64's design that made it so you had a very short amount of time to do this, making it nearly impossible to swap the game packs in time. So Rare had to scrap the idea and just put the transferable items in game packs that you could find in game in Tooie.
