Tooty

Tooty is Banjo's adorable younger sister. She's chubby with blonde hair tied up in pigtails. So far, she has only appeared in Banjo-Kazooie but she made a cameo in Banjo-Tooie on a milk carton. She was hinted to appear in Banjo-Kazooie: Nuts & Bolts, along with Brentilda, Topper, Bawl, Quarrie, and/or Colliwobble, but this was a fabrication.

In Banjo-Kazooie, she was the target of Gruntilda, who kidnapped her due to envy of her beauty. Banjo and Kazooie set out to rescue her before Grunty was able to swap looks with her. But Klungo built a machine that would switch looks with Gruntilda and Tooty. Tooty then appears looking like Grunty cause they switched looks. So Banjo and Kazooie had to defeat Grunty and get Tooty back to normal.

Beta
Tooty was originally going to be named Piccolo and was meant to be Banjo's girlfriend. In the final battle with Grunty, Grunty fires a spell at Banjo as she falls off the lair, and misses. In the beta, that spell was meant to hit Banjo, and he would be turned into a frog. Most likely, Tooty would have to carry Banjo to Mumbo to change him back. There is also a picture of her in Banjo's house. In a beta version of the game, this picture contained Donkey Kong instead.1

Trivia

 * The only cameo that Tooty has in Banjo-Kazooie: Nuts & Bolts is a sign in Showdown Town that reads "Tooty Fruity Fruit Shop", a picture in Banjos house, and on the menu screen, and mentioned some times, such as LOG mentioning he discarded a game world called "Tooty Land", and on the score board in the Jiggoseum.
