Freezing Furnace

From RWP Wiki

Freezing Furnace was the final level in Banjo-Kazooie: Grunty's Revenge. It appeared in the Spiral Mere as a pipeline and furnace covered in sheets of ice and snow. The furnace itself, called Grunty Industries, can be accessed by entering a cave. Like Freezeezy Peak, this world has icy water that causes damage to Banjo. The Octopus transformation is invunerable to this water.

Boss Battle

In the Grunty Industries furnace, you can battle Klungo. He sends out small red minions that latch onto you and cause damage. By running in circles, you can knock them off. Klungo also, like usual, has the ability to throw potions at you.
