Tooty

Profile: Banjo's little sister, as cute, sweet and innocent as Kazooie is loud, brash and shameless. Looking after Tooty is a full-time job for Banjo, as she tends to wander off as soon as his back's turned - and when he's woken one day by a jealous witch dropping onto his doorstep without warning, he can't help feeling grateful that Kazooie's so suited to the occasional wild rescue attempt...

Game Purpose: You just gotta rescue her cause that's the Main Plot of the game. I ain't gonna tell too much but I will say you don't have to kill Gruntilda to get Tooty back.
