Stop 'n' Swop II

Stop 'n' Swop II is a feature in the Xbox Live Arcade port of Banjo-Tooie and a successor to the original Stop 'n' Swop. In the game, Banjo and Kazooie can collect the Bronze, Silver and Gold Mystery Eggs which are found in the same places as the Blue Mystery Egg, Pink Mystery Egg and the Ice Key in the original game, respectively. Obtaining them unlocks in-game achievements which can be seen in the pause menu, with the first one being "Oh No, Not Again..." and the others being unlocked after it.
