Stop 'n' Swop II

Stop 'n' Swop II is the mysterious successor to Stop 'n' Swop. While the original Stop 'n' Swop used eggs in Banjo-Kazooie to unlock content in Banjo-Tooie and Banjo-Kazooie: Nuts & Bolts, the purpose of SnSII is currently unknown.

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.
