Wozza's Cave

Overview
Wozza's Cave is where Wozza the walrus lives. The cave is located in the snowy mountains Freezeezy Peak and has a variety of crystals inside it. Wozza sits next to a campfire in the middle of the cave. The Orange Jinjo is also found here. An Extra Honeycomb Piece can be found through a tunnel that Banjo can only enter as a walrus.

The legendary Ice Key can also be found inside the cave, trapped behind a frozen ice wall which can be accessed through a cheat code (CHEAT NOW YOU CAN SEE A NICE ICE KEY WHICH YOU CAN HAVE FOR FREE).

One Way In, Once
The only way to gain access to the cave is to gain Wozza's trust by showing up to him as a Walrus. He will then generously give you a Jiggy and bounce back into his warm cave. After that, you can then enter his cave as regular Banjo, since you need to be able to jump to reach the Ice Key.

Trivia

 * There is an underwater variation for Wozza's Cave, but is unused. It is possible to go underwater as Walrus Banjo, but the music doesn't change.
