Mega-Glowbo

The Mega-Glowbo, also known as Mega Glowbo, is a large Glowbo who appears in Banjo-Tooie; it has more magical capabilities than normal Glowbos. 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 or Wozza's Cave in Xbox Live Arcade version, 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, and hop in the magic pool for Kazooie to transform into the fire-breathing Dragon Kazooie.
