Boggy is a large, rather rotund polar bear that loves sledding. He often eats Jiggies and he has to cough them out. He has three kids: Soggy, Moggy, and Groggy, as well as a wife.
He is first seen in Freezeezy Peak lying on the ground near his Igloo saying he ate something. After getting up the snowman, you can use the sled to sled down the snowman's scarf and land on Boggy making him cough up his first Jiggy, literally. He then goes to the start of the first race with two sleds. Race him as a Walrus and win to obtain the second Jiggy. Then go to him in the same spot as he was during the first race and race him as Banjo (make sure you know how to use the Turbo Talon Trot first) and win to get Boggy's third Jiggy. After this, he will return to his igloo to be with his kids.
In Banjo-Tooie, Boggy and his family have moved to an igloo in the icy side of Hailfire Peaks. All he does now is sit in front of the TV. He's hungry, so he asks you to get him some food. Banjo has to use the Shack Pack to enter a boiling hot pool of water, get a fish, and then give it to him for a Jiggy (which he burps out instead of coughing it up).
Banjo-Kazooie: Nuts & Bolts
It should be noted that even though Boggy's appearance has changed drastically between Banjo-Tooie and Banjo-Kazooie: Nuts & Bolts, he still wears his orange and red scarf, although the pattern changed from boxes to stripes (perhaps as a reference to Freezeezy Peak's giant snowman who wore the same type of scarf). Along with the scarf, he is also wearing a yellow vest and a blue hat. He is a challenge host in Banjoland, the Jiggoseum, and Terrarium of Terror
