Jiggies are collectible items found in all of the Banjo-Kazooie games and can be considered the series' symbol. These golden jigsaw pieces contain a strong magic capable of breaking open the entrances to the games' worlds and are essential in progressing through each 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 in certain areas. Depending on the game, the number and manner in which the Jiggies open worlds is different.
