Snorkel

Snorkel is a dolphin in the Banjo-Kazooie level Rusty Bucket Bay that is in need of some help. He is trapped underneath an anchor and requests Banjo and Kazooie's assistance as they approach him. As Banjo and Kazooie enter the ship and hit the switch that raises the anchor, Snorkel is overjoyed to be free and rewards them with a Jiggy. Snorkel would later go on to appear in the Game Boy Advance title, Banjo-Pilot. Two dolphins who looked very similar to Snorkel also appear in the GBA title Banjo-Kazooie: Grunty's Revenge, who are possibly Snorkel's ancestors due to the time travel nature of that game.

There is also a glitch that causes the anchor to clip through Snorkel when it raises. 4J Studios did not fix it for the 360 version of Banjo-Kazooie and the graphical error still remains.
