Jiggy

Jiggies are collectible items found in all of the Banjo-Kazooie games. These golden jigsaw pieces contain a strong magic capable of breaking open the entrences to the game's worlds and are essential in moving through the game. Jiggies are obtained through completing various missions, helping characters, playing mini-games, fighting bosses, or sometimes (especially near the beginning of the games) found lying on the ground. Depending on the game the manner in which the Jiggies open worlds differs.

Banjo-Kazooie
Every level has a matching portrate hidden somewhere in Gruntilda's Lair. Jiggies fill in missing pieces of the level's portrate like a jigsaw puzzle, and an increasing number is required for each consecutive world.

Banjo-Tooie
Jiggies are taken to Jiggywiggy who has Banjo solve a timed puzzle before he opens the world.

Banjo-Kazooie: Grunty's Revenge
Jiggywiggy again but without the puzzle.

Trivia

 * The maximum number of Jiggies found in each game has decreased with each released installment with 100 in Banjo-Kazooie, then 90 in Banjo-Tooie, and only 60 Jiggies in Banjo-Kazooie: Grunty's Revenge even less are found in Banjo-Pilot


 * In Banjo-Kazooie, when Banjo obtains a Jiggy, he will jump around dancing while holding it above his head stopping just long enough for Kazooie to eat it. The only exceptions to this rule are when A) Banjo is in the air or underwater or B) In a transformation while obtaining the Jiggy. In Banjo-Tooie however, the Jiggy spins around Banjo before flying into the air and dissapearing without disrupting gameplay. This new method could be easier to program and used for any character or situation in which the Jiggy is obtained without looking wierd if used on unusual terrain (ex. while sliding down a slope).
