Like the original Stop 'n' Swop, Mystery Eggs are collected in one game to be used in another. In SnSII's case, these eggs are Bronze, Silver and Gold. The SnSII eggs are found in the same locations that the Blue Mystery Egg, Pink Mystery Egg, and Ice Key were found in the original Banjo-Tooie. Unlike the original Stop 'n' Swop instead of showing the items on an item subscreen it lists them, also included in this list are additional achievements.
