Toadette is a female Toad that helps out Mario by giving tutorials on upgrades to his boots or hammer. She's very enthusiastic about her work, and is very excited to be helping out Mario.

I think Toadette's voice should be pretty standard to what she's sounded like in other games. She sounds similar to Toad, but not necessarily with the same amount of rasp all the time.

This role will have a short chunk of lines every once in a while (whenever Mario gets a boots or hammer upgrade, which should be in Chapters 2, 3, 6, and 7).
