Temple Test Level

Giant's Lair is a test level believed to be an early version of Grunty's Lair. It takes place in a towering temple somewhere in an oasis-like area.

Many players get Giant's Lair confused with Mount Fire Eyes, another beta level from Banjo-Kazooie. Furthermore, hackers discovered an unused theme in the game known as "Advent," and many people also mistake it as the theme of the beta level Fungus Forest, when in reality it was intended to be the theme for the Giant's Lair.
