Gloop

Gloop is a friendly blue fish from Clanker's Cavern in Banjo-Kazooie. He supplies Banjo with air in the form of bubbles while the bear tries to raise Clanker by swimming through a key deep under water. He blows sequences of bubbles followed by a short rest. In his journey he swims through the keyhole so some fans wonder why he does not free Clanker.

Many players believe that the fish found in Hailfire Peaks that is needed to feed Boggy could in fact be Gloop because of its striking resemblance to the bubble-blowing fish.
