Banjo: The bear that has stared in Banjo-Kazooie and Banjo-Tooie, appeared in
Diddy Kong Racing, and Conker's Bad Fur Day (As a hunting trophy in the pub) is
back on the GBA.
Kazooie: The foul mouthed one returns as well! Although you don't have access
to her at the start of the game. She's there to assist Banjo on his adventure,
it might look like Kazooie's doing all the work, but Kazooie needs Banjo's
assistance to do most of her moves, likewise Banjo!
Mumbo: The Shaman returns to be the lazy shaman he was in BK instead of
adventuring out in BT. He's there to transform you into 4 different animals,
but he needs a Mumbo Totem for his magic to actually work
Bozzeye: Bottles (from BK/BT) distant cousin is there to help Banjo and
Kazooie relearn moves from BK, as well as learn new ones, although it comes at
a price --- notes, which aren't hard to find, but is there a reason he would
Grunty: The witch from BK is back, in her new mecha suit! You face her a few
times in the game, and she 'upgrades' as well.
Klungo: Grunty's assistant is there to help Grunty with all of her dirty needs.
You face him as a boss as well sometimes.
Jiggywiggy: He's there to help you open the worlds with the Jiggys you collect.
Honey B: Hollow honeycombs is what she likes, and she will trade them to
increase your energy bar.
Jinjo Oracle: He is there to give you clues and information about finding
Jiggies and Jinjos, but in order for him to give you information, you need to
show him your dedicated to saving Jinjos--- by naturally, saving them.
