Lyrics
Candy: Gather round and let us sing
about a girl, who had almost everything...
Dipper: Look, it's Mabel!
Mabel: Hi there!
Soos: Did you say stable?
Stan: No, he said Mabel!
Mabel: Ok, hit it boys!
Who's that girl with the pig and braces
She puts smiles on everyone's faces
When she's around you're never bored
Mayor: I am a mayor, here's an award!
Mabel: Thank you, mayor. It's true I'm great
But the perfect girl, needs the perfect maaaaaaate!
Gabe: Hey wassup, I'm Gabe.
Mabel: WHAAAAAA?
