Gloop

"Hi, I'm Gloop! Grab my bubbles if you're low on air!"

- Gloop

Gloop is a friendly blue fish from Clanker's Cavern in Banjo-Kazooie. He supplies Banjo and Kazooie with much-needed air in the form of bubbles while the bear and bird try to raise Clanker by swimming through a key deep underwater. He blows sequences of bubbles every few seconds followed by a short rest.

Interestingly, Gloop cannot free Clanker despite being able to swim through the key needed to free him.

Trivia

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