Gloop

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

- Gloop

Gloop is a friendly blue fish who lives in the lowest regions of Clanker's Cavern in Banjo-Kazooie. It swims around in an underwater pit where Clanker is chained from.

Gloop spits out a sequence of air bubbles that refill Banjo and Kazooie's oxygen supply. Gloop does this every few seconds, followed by a brief pause. The air bubbles give Banjo and Kazooie enough time to swim through the large key three times, which unlocks Clanker's chain.
