The Legendary Ice Door, which contains the Legendary Mega Glowbo, that can be unlocked by the Legendary Ice key, is found in Hailfire Peaks Icy Side, but is only accessible by linking to there from Glitter Gulch Mine. Confusing, right? I will explain everything. First, you will need the Ice Key. See the Ice key page for details on how to get it in the Nintendo 64 version or the XBLA version. The Ice Door contains the Mega Glowbo which can be given to Humba Wumba in Pine Grove to transform Kazooie the Red-Crested Breegull into Dragon Kazooie. Detailed instructions on how to do this can be found on the Ice key page. Sorry about the bad quality picture, it's hard to find a picture of the Ice Door, but don't worry, it's really hard to miss in-game.
