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 entrances 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 portrait hidden somewhere in Gruntilda's Lair. Jiggies fill in missing pieces of the level's portrait 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. An increasing number is needed for each consecutive world.

Banjo-Kazooie: Grunty's Revenge
Jiggywiggy again opens the worlds, just like in Banjo-Tooie, but solving a puzzle is no longer required.

Banjo-Kazooie: Nuts & Bolts
Jiggies are taken, from the Jig-o-vend units, to the Jiggy Bank in the Central Plaza of Showdown Town, to open the world act doors, and (like the previous games), an increasing number is needed on every door.

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. 131 jiggies are total in Banjo-Kazooie: Nuts & Bolts and gain a gamerpic when collecting all the jiggies.


 * 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 strange if used on unusual terrain (ex. while sliding down a slope). In Banjo-Kazooie: Nuts & Bolts when you gain a Jiggy and bring it to the Jiggy Bank, it floats into the bank, playing the jingle from the first 2 games. Jinjo!
