In the Xbox Live Arcade port of Banjo-Tooie, the Silver Secret Egg is found within a Banjo-Kazooie Game Pak in Spiral Mountain, located in the cave behind the waterfall. When collected, this item unlocks the "Better Than a Slap" menu item on the Stop 'n' Swop II menu screen. When the Silver Secret Egg is collected, Jamjars comments, "Well, well, well! It's a very flashy Silver Egg! Better keep that in a 'save' place."
