Boggy's Gym

"Hello you two. Mrs. Boggy kicked me out to earn my keep, so I bought this old gym from Mr. Fit as an "investment." Find enough Notes and you can work out here to upgrade your abilities..."

Boggy's Gym is an outlet located near the Docks of Showdown Town, being owned by Boggy. It was bought from Mr. Fit after Mrs. Boggy kicked her husband out of home and forced him to get a job so he "earn [his] keep."

In Banjo-Kazooie: Nuts & Bolts, Banjo and Kazooie can pay Boggy Musical Notes to upgrade their speed, strength and stamina three times each, allowing them to run faster, deal more damage to enemies and also carry heavier vehicles without slowing down, and be able to take more damage or stay underwater for more time before being knocked out, respectively. Boggy does not allow the duo to upgrade any ability a fourth time, as he claims he can't teach them any more speed upgrades, they'll "look freakish" and that they "might explode," for each respective attribute.

If all strength upgrades are acquired, the weight of a vehicle does not reduce the speed at which Banjo moves while Kazooie is using her magic wrench to carry vehicles.

Stamina upgrades prevent fall damage from being able to defeat Banjo at full energy, as fall damage has a cap that doesn't increase with his maximum energy, thus a fall that would cause Banjo to pass out even at maximum energy, would, with all three stamina upgrades, only reduce his energy to half. He can still be beaten by fall damage if his stamina is low, or, contrary to most games, if he splits his falls into smaller segments.

Atop the gym, a Mumbo Crate containing a British Flag vehicle part appears once the console has a save file of the Xbox Live Arcade release of Banjo-Kazooie with the Ice Key collected.
