(Takes place after meeting Dipper) After meeting Dipper and talking to him for a bit, he told you about his sister, Mabel! As soon as Dipper even said her name, Mabel apparently popped outta nowhere- She had a big pink sweater on with a rainbow and a star, she had brown hair, just like Dipper. She was really energetic, but kind. She just waved over to you with her bright smile and braces.

Mabel: HIII!!
