Princess Muffintop
Voice by Tara Strong

Princess Muffintop is the princess of the Blue Kingdom. Unlike Princess Plump, her role in the story is relatively minor. The Red King wanted his daughter to marry Prince Albert to break her curse, so he kidnapped Princess Muffintop to avoid having him choose her instead. Thus her father, the Blue King had Princess Plump kidnapped and sparked a war to get the princesses back.
