Princess Sofia is the main protagonist of the Pooh's Adventures of Sofia the First: Once Upon a Princess.
She Will Be a Team Member of The ToonTown Rebel Resistance.

While cute and beautiful, Sofia is rather clumsy but has a pure heart. Since she was originally a mere commoner, she retains a very carefree persona, and was once seen to enjoy sliding down the rails of the staircase. Her outcast-esque behavior often puts her at wits with her stepsister Amber who's apparently jealous of Sofia.
