Master Jiggywiggy

Master Jiggywiggy is the keeper and protector of the Jiggies and the Crystal Jiggy in the Banjo-Kazooie series. He can be found in Jiggywiggy's Temple. He wears a bright yellow tunic and a bright blue cloak with Jiggy images on it held up by a honeycomb-shaped brooch, and his head resembles a Jiggy. Master Jiggywiggy has a disciple named the Disciple of Jiggywiggy.

Banjo-Tooie
In Banjo-Tooie, whenever Banjo and Kazooie have enough Jiggies to unlock the next world, the Disciple of Jiggywiggy allows them to enter Jiggywiggy's Temple. In there, Master Jiggywiggy tasks Banjo and Kazooie with a jigsaw puzzle challenge, which they must complete within a time limit. If the duo are successful, Master Jiggywiggy uses the Crystal Jiggy's power to unlock the doorway to the next world.

Banjo-Kazooie: Grunty's Revenge
In Banjo-Kazooie: Grunty's Revenge, Master Jiggywiggy reveals that Gruntilda has cursed the Jiggy priests. This curse prevents him from touching the Jiggies, so he relies on Banjo and Kazooie to collect the Jiggies instead. Other characters resembling Master Jiggywiggy are located in Jiggywiggy's Temple, but they all wear plain brown robes. When Banjo and Kazooie have a certain number of Jiggies, Master Jiggywiggy allows them to activate the Crystal Jiggy to open the next world.

Banjo-Pilot
In Banjo-Pilot, Master Jiggywiggy makes a cameo appearance as one of the character in the winner's circle.

Banjo-Kazooie: Nuts & Bolts
Although Jiggywiggy himself does not appear in Banjo-Kazooie: Nuts & Bolts, Jolly Dodger does sell a Jiggy named "Mr. Jiggywiggy."

Banjo-Kazooie: Grunty's Revenge
Banjo: Okay, I'll go get more Jiggies.
 * "You have just collected your first Jiggy. Jiggies are powerful objects containing magic strong enough to break the spell of the great witch Gruntilda. Gruntilda has scattered our Jiggies far and wide across many lands. The spell that she cast on us Jiggy priests prevents us from touching any Jiggies, so we are powerless to stop her. The Jiggy that you've just collected has enough power to open the way to Cliff Farm. I will open the gateway to the altar for you - please carry this Jiggy to the Jiggy pad and press A to release the Jiggy magic."
 * "Please hurry to the Jiggy altar and press A to open the other worlds! Gruntilda cannot be allowed to win."
 * Jiggywiggy: You can't open the way to the next world yet. With 6 Jiggies you should be able to break Gruntilda's seal.

Trivia

 * In Banjo-Tooie, if Banjo and Kazooie use cheat codes to open a door to another word, then Jiggywiggy proclaims that another force has opened the door.
 * If Banjo and Kazooie constantly fails Jiggywiggy's Challenges, he claims they are perhaps not the chosen ones, so Master Jiggywiggy decreases the puzzle's difficulty level.
