Grunty's Castle is the last level of Banjo-Kazooie: Grunty's Revenge. It is a very old version of Gruntilda's Lair set 20 years in the past and is only accessible through a Witchy Warp pad in the hat's doorway. A nearby head of King Jingaling suggests that it used to be suspended in place of the Grunty head. Some speculate this as a sign of the entire Jinjo population living in Spiral Mountain .

A nearby head of King Jingaling suggests that it used to be suspended in place of the Grunty head. Some speculate this as a sign of the entire Jinjo population living in Spiral Mountain . Upon entering there are 3 battles. One with Gruntilda, one with Klungo, and then finally a final battle with Mecha-Grunty on the castle's roof. A short quiz show of three to five questions separates the fights. This is usually called "Grunty's Quiz".
