The short, blue-wearing fairy from Disney's Sleeping Beauty. She's the one with a temper, and the evil horned queen calls her "the rebel." It's her spell that turns Princess Aurora's dress blue and alerts the queen's crow where they are all hiding.
Tanya: (while watching Sleeping Beauty) Wait, what's the blue one's name?
Joe: Merryweather. And I can't believe you're making me watch this with you.
