Banjo-Kazooie Tips

20 Gold Feathers
Speak to the third spell book by activating the 321 switch above the pool leading to Click Clock Wood and then swimming to the stairs near Rusty Bucket Bay. You'll need to be quick as this is timed. When you've spoken the book, go to back to the sandcastle on Treasure Trove Cove and enter "GOLDFEATHERS" on the sandcastle floor in the same way as you did the previous two codes.
