Dragon Kazooie

Dragon Kazooie is a secret transformation in Banjo-Tooie that you get if you give Humba Wumba the Mega Glowbo, obtainable only by unlocking the Ice Safe with the Ice Key. However, this transformation does not work on Banjo. Instead, it turns Kazooie into a fire breathing dragon! This transformation is different from the rest, as it can go into every world, and is the only transformation that specifically affects Kazooie. By holding down while standing still, Kazooie can breathe fire, and she also has an infinite amount of Fire Eggs. Her voice also deepens a bit in pitch.

Trivia

 * While Kazooie's outward appearance dramatically changes, her shadow bizarrely stays in the shape of a normal breegull. Her character portrait when speaking also stays the same. However, when she splits up from Banjo, her shadow becomes representative of her dragon-like appearance.
 * Kazooie's voice is much more deeper than what it used to be but when she is talking her voice will be the same as normal Kazooie.
 * In the Xbox Live Arcade version of Banjo-Tooie, you need to unlock and collect the Ice Key from the XBLA version of Banjo-Kazooie to open the safe where the Mega Glowbo is hidden.
