Then press R and the bottles should start talking. If you have the Jiggy from the sandcastle in Treasure Trove Cove you can play a mini-puzzle game. You have to put together the puzzle and then go back to Treasure Trove Cove. In the sandcatle, spell out BOTTLESBONUSONE. Banjo's head will get bigger. Spell NOBONUS and it will reverse it. Also if you want Big arms and legs spell BOTTLEBONUSTWO.

20 Gold Feathers

Thanks to jcbc for this code

All you do is go to the Rusty Bucket Entrance. To the right 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. 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 will have to be quick because you will have a limited amount of time. In the cave to your right you will find a spellbook which will give you the code "GOLDFEATHERS". You must enter it in the Sandcastle on the Treasure Trove Cove level. Note: To enter the code you must have first received the puzzle piece from the Sandcastle by talking to the bucket on the ledge near the sandcastle and shooting two eggs from your butt(hold z and press down c) into the bucket. He will then drain the water. Then enter the Sandcastle. You will find letters on the floor. Enter "BANJOKAZOOIE"by doing beak busters (jump by pressing B and press z while in the air)on the letters. You will then recieve a puzzle piece. Then go out and back in and enter the code on the tiles. You will recieve a max of 20 feathers instead of 10. IF YOU LEAVE TREASURE TROVE COVE THEN YOU WILL HAVE TO DRAIN THE WATER AGAIN.

Be a Washing Machine

If you beat the puzzle game six times the bottles will say, "That's all folks." Don't let him trick you. There is still one more game and you have to beat it. Then go to the Sandcastle and spell WISHYWASHYBANJO.

Get 200 Eggs

Go to the Bubble Gloop Swanp. Change into the Alligater. Then go out of the level. Then go behind the level and find the pipe that takes you to the puzzle board. Go in the pipe and at the top of the hill talk to the book. Then go to the Sandcastle and spell BLUEEGGS. Note: This will only work if you talk to the book.

Get 100 Red Feathers

Go into Mad Monster Mansion, and have Mumbo turn you into a pumpkin. Exit the level, while you are still a pumpkin. When you get to the lava filled room, go the opposite way that you went in. Be careful that you don't fall off of the bridge, because it's very narrow. If you make it to the end, you will see Brentilda and a small hole. The hole leads to a tunnel, and the second spell book is there. Enter the code: REDFEATHERS on the sand castle floor. It gives you 100 red feathers.
