Mega-Glowbo

At first glance, the Mega-Glowbo may look like just a very large Glowbo, but it is a source of extraordinary magical power. Once the Talon Torpedo has been learned from Jolly Roger's Lagoon, and the Ice Key has been collected from the Banjo-Kazooie Game Pak in Jinjo Village, return to Glitter Gulch Mine and break the boulder with Kazooie's face on it (in the waterfall cavern) using the Talon Torpedo. This will uncover a tunnel leading to a small room on the icy side of Hailfire Peaks with a giant safe made of ice. The Ice Key will unlock the safe, revealing the Mega-Glowbo.

Take the Mega-Glowbo to Humba Wumba within the Pine Grove, just outside the entrance to Witchyworld, and hop in the magic pool to transform Kazooie into the fire-breathing Dragon Kazooie. The Mega-Glowbo cannot be used in place of a regular Glowbo and can only be used in the Pine Grove.
