Glowbo's are collectible items in Banjo-Tooie. They are small pink magical creatures with green eyes. They give Mumbo and Humba their powers and replace the Mumbo Tokens from Banjo-Kazooie.
Two Glowbos appear in each level, one for each Shaman. Fortunately, they are generally found near either Mumbo's Skull or Humba's Wigwam. There is also one Mega-Glowbo in the game, hidden in the glacier side of Hailfire Peaks that can only be acquired by going through Glitter Gulch Mine. Giving the Mega Glowbo to Humba Wumba in her wigwam outside of Witchyworld allows Kazooie to transform into Dragon Kazooie.
