Din-Din

From the Banjo-Kazooie Wiki, the largest Banjo-Kazooie info resource.

Din-Din is a fish that must be taken to Boggy. He is found in one of the two pools of boiling water in the Hailfire Peaks level (on the far left side). To get him Banjo must use his Shack Pack ability. When Banjo brings the fish back to Boggy, Boggy eats it and then coughs up a Jiggy that Din-Din ate. Many gamers believe this fish to be Gloop or made from Gloop's design because of the similarity between the two.
