Banjo's Double Jump
While playing with Banjo, without Kazooie in your backpack, jump then use the "Pack Whack" attack, then jump again. Banjo should now do a second jump. NOTE: You must have learned the "Pack Whack" attack, or this will not work.
The Secret Items/Eggs
There are 3 special, secret N64 cartridges in Spiral Mountain and Jinjo Village. They each hold a "mystery" item from Banjo-Tooie, the Ice Key, Pink Egg and Blue egg. Here is how to locate them.
For Cartridge 1 and the Blue Egg, use the fly pad at the tip of spiral monuntain to fly into the cave in the smaller of the 2 waterfalls. In the area there, there is a small ledge. Flip flap jump and grip grab the ledge, then follow it along into a tunnel. in the tunnel is the Game Pak with the Egg inside, roll into it to free the egg.
For Cartridge 2 and the Pink Egg, use the fly pad and airborne aiming sight to launch a egg at the padlocked door directly opposite Gruntilda's old lair. In there is the Cartrige, roll into it to free the egg. These 2 eggs can be brought to Heggy's egg shed, located by following a path directly opposite Mayahem Temple's entrance in Wooded Hollow. Heggy hatches the 2 eggs and gives you a new move (Breegull Bash) and a code (homing Eggs).
As for the third and final Cartridge with the Ice key, it is in Jinjo Village. There is a small ledge in the sandy area behind the green house. Grip grab the ledge and follow it to reach a cave with the cartridge. Smash it to reveal the Ice Key, which i am not completely sure what to do with....
Oh! and by the way..... once you have the Hatch move for Kazooie and the Split Up and bill Drill moves, go back to heggy's shed. If you didnt already notice, there is a ed piece of shell on the floor. Use the Bill Drill on it to reveal a Split up Pad. Split the pair, and use kazooie to hatch the yellow egg on the second floor of the egg shed. after doing this, the jinjo can be used in multiplayer battles. Enjoy these secrets.
Swim faster
Press A + B to swim faster in water.
Open all doors on Hags
To open all of the doors on the island of Hags, use the password "cheatojiggywiggyspecial" in all capital letters. *Note* Be careful! Just because you opened a door, that doesn't mean that you could do everything in that world! You still have to learn special moves from Jamjars if you want to do anything or get anywhere.
Multi-Player Jinjo
Ok, all of this talk about Heggy's Hen House has likely got you wondering what is in that egg up top. Well, once you learn the Hatch move in Terrydactyland head back to Heggy's place, Bill Drill the object on the Split-Up Pads, Split-Up ad have Kazooie Hatch it. Inside you'll find a Jinjo that can be used when playing multi-player.
Drive Submarine on Land
Okay, this may be useless, but it's still kind of neat. Have Humba Wumba transform you into the Submarine in Jolly Roger's Lagoon. If you try to warp back to the Town Square, you will be told that submarines can't operate outside the water. Not true! You can take the sub manually up to the surface and drive up the slope. The underwater craft actually handles quite well on dry land. Sadly, you can't get up the stairs -- but you can hop into the pig pool and explore the docks at your heart's content.
Invincibility
Enter cheatcode "HONEYKING".
Kazooie can go underwater
First, get the the backflip with kazooie in Grunty Industries. Then go to Jolly Rogerers Lagoon and run up to the tip of the lagoon without stoping and backflip (Z+A). Kazooie will be sinking down.
Note: When you hit the ocean floor, you will float back up.
