It's possible to bust the boulder blocking the Beaver's hole in Click Clock Wood on the Sping Level (The first level you have access to). If you stand up on the ledge above the rock and get at just the right angle a little to the right of the rock and drop eggs out of Kazooie's butt onto the boulder, you can blow it up. If you swim into the hole on this level it gives you some strange game glitches, and the Beaver will still beg you to move the rock even though it's gone.

First go to the Rusty Bucket Bay entrance. Then look to the right and you will see a cave with three pipes. Break the one in the middle and go into the pipe. At the opening you will see a switch that will raise the water level once you pound it down. After you activate the switch you will have to jump out into the water and go to your right, and you have to be quick because you have a small amount of time. In the cave to your right you will find the third spellbook which will give you the code "GOLDFEATHERS." You must enter it in the Sandcastle on the Treasure Trove Cove Level to activate the 20 feathers.
This code (sort-of) allows you to view a new, funnier opening to the game. Before you start your game, all you have to do is watch the fish swimming around in the fish-bowl.

On the first game save, Banjo will be thrown out the window and on the second the wall will spin around causing Kazooie to be chucked outside. The third game save you must listen for the BOING sound coming from the Gameboy, the third time you hear it, press A and a giant spring will come out from the the bottom of the chair, launching Banjo out of the house.
