Stop N Swop in the Banjo-kazooie series
in the first Banjo-kazooie on the N64, putting in secret codes in the sand castles floor will open up areas leading to 6 colored eggs and a ice key.
If you beat Banjo-kazooie with all 100 jiggys, Mumbo will show a few picture videos where few of the eggs and the ice key can be found.
2 of the eggs and the ice key can be obtained in Banjo-tooie, The ice key is used to gain one of those pink things but the one you get with the ice key is larger. It can be used to turn Kazooie into a dragon.
You can get both Kazooie and Tooie on xbox live. If you collect the eggs in Banjo-kazooie if you have Nut's & Bolts, Bonus parts will be unlocked found in a few areas of showdown town.
If you go to the areas where the 2 eggs and the ice key were in Banjo-tooie, There will be a Bronze, Silver and a Gold egg. These are part of the games achievements.
