Rare's Mr. Pants Cameo
Once you have gotten Hailfire Peaks unlocked, go to the ice side of it. Search around until you see Boggy's hut (it's a giant igloo). Go inside and look at the TV that Boggy is sitting in front of. You should see this white man with a hat and nothing but pants on. This is Mr. Pants, by Rareware.

Secrets
Accessing Dragon Kazooie: Once you've found the mega glowbo from the ice chest, go (or warp) to Pine Grove and enter Humba Wumba's wigwam just outside of witchyworld. Give her the mega glowbo and Kazooie will be transformed into a dragon, which is much more powerful than normal Kazooie. Jump in the pool again to return Kazooie to her normal state.
Character select and options: If you want to play as other characters such as Grunty, simply select single game then a shootout. Select pick characters and press <- or -> to see various characters. There are also other options in single game.
Free Hotel Room: To get Jolly Roger's room for free in Jolly Roger's Lagoon, just shoot the door with a grenade egg instead of paying. He'll yell at you, but nothing else.
Getting the Mega Glowbo: To get the Mega Glowbo, first you must have the Ice Key and you must know how to use the Talon Torpedo ability. Once you have the Ice Key and this ability, go to Glitter Gulch Mine and hit the switch near the entrance to open the grating which leads to the Water Storage area. Run to the grating before it closes and go inside. Talon Torpedo the big boulder underwater and go through the tunnel into Hailfire Peaks. Climb up the small hill and unlock the Ice Chest to get the mega glowbo!
Stop 'n' Swop II: Find and collect all six secret eggs in Banjo-Kazooie, then go back to Banjo-Tooie and go to Heggy's Egg Shed. Allow Heggy to hatch all six eggs and you will be notified that Stop 'n' Swop II has been found.
