|Appearance||A blue/turquoise, fat fish|
Gloop is a fish found in Clanker's Cavern, under the water in the area where the giant key is. While Banjo and Kazooie try to raise Clanker up, Gloop supplies air bubbles for Banjo and Kazooie. Banjo can swim through the air bubbles to get air.
In Banjo-Tooie, Boggy the polar bear wants fish. Banjo gets Boggy a fish from Hailfire Peaks (Lava Side) at the bottom of a pool filled with hot water. This fish is Gloop but he had turned yellow from being fried in the boiling water.
