Mr. Fit

Mr. Fit is a gray aardvark with a hobby of fitness and racing, and he wears a purple tracksuit. Mr. Fit first appears in Banjo-Tooie.

Banjo-Tooie
In Banjo-Tooie, Mr. Fit is found at Cloud Cuckooland. Here, he challenges Banjo and Kazooie to three sporting events. The first event is to leap over a pole, which he somehow set his best high jump on. Since the pole is so high, the two will have to use Springy Step Shoes to make the leap over the pole, landing on a red jelly. Distraught, Mr. Fit invites the duo to the next event.

In the second event, Mr. Fit challenges the two to a sack race over a path of thorns. Banjo will have to Split-up and return alone with the Sack Pack. There's a shortcut he can take to quickly get to the finish line. Confidence lost, Mr. Fit will go to the last event.

In the third and final event, Mr. Fit holds a footrace. The only problem is that he's too fast for Banjo or Kazooie to beat, so Kazooie will have to use Split-up and return with the Turbo Trainers, or use the SUPERBANJO cheat and do Kazooie alone, or the duo with Turbo Trainers. When he reaches the finish first, Mr. Fit will admit defeat and give the duo a Jiggy.

Banjo-Kazooie: Nuts & Bolts
Mr. Fit reappears in Banjo-Kazooie: Nuts & Bolts and has a larger role than in his debut appearance.

At Showdown Town, Mr. Fit runs in a set path. When he stops, he offers you a Trapdoor Tower combination so he can buy new sneakers. It is possible to catch him without the trolley, as the player runs about 5% faster than him. He still wears his purple track suit.

At Nutty Acres, Mr. Fit acts as a mechanic on the farm and seems to be only one besides Humba Wumba that does their job. He wears a green suit in this world but the pants are muddy. He hosts challenges in Acts 4, 5 and 6. He first needs protection on his jog around the island, then he challenges Banjo to gather more coconuts than him. In the final act, he hosts a water race against the entire farm staff. Fit is still a braggart in this world, although is also paranoid about the Gruntbots. He has a rivalry with Trophy Thomas, as the two compete for Farmhand of the Year Award.

At Banjoland, Mr. Fit appears here as a greeter, even though he is never seen at the front door. He instead waits at the kickball field. He wears a green jumpsuit with a small Jiggy on it in this world. He hosts challenges in Acts 2, 3, 5, and 6. He first challenges the bear and bird to kick soccer balls into a goal. Then he needs Banjo to turn the security cameras on for the night. After that he wants Banjo to drive a Gobi vehicle around the museum. lastly, he needs Banjo to play golf with a round sheep. He continues his paranoid tendencies because he is afraid of Banjoland at night. He likes his job but is never actually seen doing it, probably because no one ever visits Banjoland.

At Jiggoseum, Mr. Fit is one of the competitors. He wears a white track jacket and shorts that have the British flag on them. He returns to his competietive self as he has another rivalry with T.T. he hosts challenges in Acts 1 and 3. He first challenges you to a long jump challenge. After that he wants you shoot basketballs through a hoop. He also appears as another racer in Trophy Thomas' races.

At L.O.G.'s Lost Challenges, Mr. Fit plays a High-Tech Infiltrator in this world. His only challenge is a basketball like game where you have to carry a basketball through hoops to beat his high score.
