Cheato

"Witch lost book, finders bear and bird are, spell they get!"

- Cheato

Cheato is the magical spell book of Gruntilda. His main role is to provide cheat codes for Banjo and Kazooie to use against Gruntilda in the first two games.

Banjo-Kazooie
Cheato makes his debut appearance in Banjo-Kazooie. Banjo and Kazooie encounter him while exploring Gruntilda's Lair. Cheato is unhappy with Gruntilda's abusive behavior toward him, so he decides to abandon her and help Banjo and Kazooie instead. Cheato can be found in three different areas throughout the lair, which are hard to reach through regular means or require the use of a certain transformation. Each time Banjo and Kazooie find Cheato, he rewards them with a magic spell, or cheat, which allows them to significantly increase the maximum capacity of eggs and feathers that they can carry. Gruntilda threatened to destroy Cheato for helping the duo, but she was defeated before any damage could be done.

These are the three cheats that Cheato provides to Banjo and Kazooie:
 * BLUE EGGS - Near the Freezeezy Peak puzzle, Banjo must enter a tunnel as a crocodile after destroying the ice block.
 * RED FEATHERS - In the lava room, follow the small winding path to a small tunnel as the pumpkin.
 * GOLD FEATHERS - In the Rusty Bucket Bay entrance room, Banjo must raise the water level to 3 and then go to the alcove before time runs out.

Banjo-Tooie
In Banjo-Tooie, Cheato is found in the remains of Gruntilda's Lair in Spiral Mountain. Gruntilda ripped out most of Cheato's pages because he provided cheats to Banjo and Kazooie in Banjo-Kazooie. His pages are appropriately known as Cheato Pages, which are scattered around the Isle o' Hags. For every five pages that Banjo and Kazooie return to Cheato, he gives them one cheat. Banjo and Kazooie can activate cheats in Mayahem Temple's Code Room. Furthermore, the duo can input "CHEATO", followed by any known cheat spelled backwards, to activate it regardless of whether the cheat has been unlocked or not.

Banjo-Pilot
In Banjo-Pilot, Cheato has lost his pages again. The player can acquire them from finish races, and return them to Cheato in exchange for unlockable characters and features.

Banjo-Kazooie: Nuts & Bolts
"Hapless page-shedding spellbook, mistreated minion of Grunty and veteran of the Banjo-Kazooie series. Returning Cheato's pages tended to earn unlockable items or, surprisingly, cheat codes."
