Alright, so, Stop and Swop is in Banjo Tooie. You do not need N&B to access the Stop and Swop items in Banjo Kazooie. These places unlock from one of three ways:
- if you had NaB, they were already unlocked.
- if you bought Banjo Tooie, they will unlock.
- if you got the secret ending of mumbo showing you the flip book of stop and swop items, they will unlock.
So if you go into Banjo-Kazooie, and you have opened the stop and swop items, you simply need to touch them (not easy to do for the one in treasure trove cove, but the rest are easy to get to).
After that, go into Banjo-Tooie, and play up unto you meet Heggy. Then talk to her and she will then proceed to hatch your eggs, one at a time (you must talk to her 6 times to hatch all the eggs). They will unlock in some order:
- a gamer pic
- a gamer theme
- the homing egg cheat
- the breegull bash
- jinjo in multiplayer
- and lastly: a hint at a new game.
