Cheato

Cheato is Gruntida's magic spellbook. He is found in Banjo-Kazooie, Banjo-Tooie and Banjo-Pilot. He is responsible for giving Banjo and Kazooie Cheat Codes to use against Gruntilda in the first two games and unlocks extra features in Banjo-Pilot.

Banjo-Kazooie
In Banjo-Kazooie, Cheato gives you three cheat codes: BLUE EGGS, RED FEATHERS, and GOLD FEATHERS. He will give these to Banjo and Kazooie if they can find him hidden in Gruntilda's Lair. The cheats can only be activated once found.
 * BLUE EGGS - Near the Freezeezy Peak puzzle, enter the tunnel as the crocodile AFTER the Ice block had been destroyed.
 * 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, raise the water level to 3 and then make it to the alcove before time runs out.

Banjo-Tooie
In Banjo-Tooie, Gruntilda has carried out her threat of ripping out Cheato's pages for giving cheats to Banjo and Kazooie in the previous game. Banjo and Kazooie must find his missing pages and return them to him so that he can provide them with more cheat codes. For every five pages that are found, Cheato will give Banjo and Kazooie one cheat. The cheats can only be activated in the Code Room of Mayahem Temple.

An interesting thing to note is how exactly Gruntilda managed to rip out Cheato's pages. She was previously trapped under a boulder for 2 years after the events of Banjo-Kazooie. Later when she was freed by her sisters, she left Spiral Mountain without visiting her lair. It is possible that she may have ripped out Cheato's pages before kidnapping Kazooie in Banjo-Kazooie: Grunty's Revenge, as it is set in between Banjo-Kazooie and Banjo-Tooie.
