Let's say that in Banjo-Tooie we find something really, really hot. Then, let's say we Stop 'N' Swap it to Banjo-Kazooie, then we melt the ice wall with it and get the Ice Key, which we Stop 'N' Swap to Banjo-Tooie! Using it, we head through a door, and find we need two jiggies. So, we turn on Banjo-Kazooie, and Stop 'N' Swap the two extra jiggies to Banjo-Tooie, then use them! We pick up a chunk of ice... which we Stop 'N' Swap to the original game. We drop it in the lava pit, then it solitifies and we jump down there, and find a cave to the lava world! Using this incredible feature, we may find more worlds in the original game! Maybe a lava world! Rest assured, we will be stopping and swapping alot... those guys at Rare are simply geniuses.
