Stop 'n' Swop

Of all the secrets and mysteries in the Banjo-Kazooie series, none are more tantalizing or more talked about than Stop 'n' Swop. More rumors have circulated about it than about the large doors at the top of Gruntilda's Lair, and although most of them - both the silly and the sensible - are false, there are some truths in the clutter. The mystery involves six brightly colored "Mystery Eggs" and a large key made of ice found in Banjo-Kazooie, and their alleged use in its sequel, Banjo-Tooie. It has also been revealed by the Rare team at E3 08 that the version of Banjo-Kazooie being release on the Xbox live arcade will implement the Stop 'n' Swop feature as it was originally intended, however it will be used in correspondence to Banjo-Kazooie: Nuts & Bolts

Banjo-Kazooie
At the end of Banjo-Kazooie, if all 100 Jiggies have been collected, Mumbo Jumbo will show the player three animated photographs which reveal the locations of two Mystery Eggs and the Ice Key as being in places which the player can see in Banjo-Kazooie, but not access by normal means. Fortunately, there are codes within the game which can be entered on the Sandcastle floor in Treasure Trove Cove that will allow anyone to reach these treasures, as well as the other four eggs not mentioned by Mumbo Once the items are collected, they are placed into the STOP 'N' SWOP inventory which can be seen in in View Totals just after the totals for Click Clock Wood.

A note: once the codes have been entered and the items collected, they will appear on every game file on the cartridge and cannot be removed, even if all files are erased. Another interesting note is that in the Xbox Live Arcade version of Banjo-Kazooie, once someone buys Banjo-Kazooie: Nuts and Bolts, all the doors to the secrets are automatically opened.
