Every level has 5 Jinjos (Purple, Blue, Yellow, Green, and Orange) Banjo must save. After saving the 5th one, a Jiggy appears and the Jinjos "reunite".
Jinjos have now been broken up into families (Orange, Yellow, Green, Blue, Red, Purple, Black, Brown, Grey, and White). When Gruntilda's drill went through Jinjo Village, it destroyed the Grey Jinjo house, killing the entire family. Unlike the first game, some Jinjos are actually their evil counterpart: Minjos.
