Strawberry Shortcake: Let's Dance (2007)

Strawberry and her friends love to dance - and the Peculiar Purple Pie Man of Porcupine Peak is taking advantage of that! He has Sour Grapes open a phony Dance Studio, posing as a famous teacher so she can keep the kids busy while he plunders the berry crops. But things don't go as planned. Sour Grapes begins to enjoy teaching Strawberry and friends and can't bring herself to betray them, much to Pie Man's chagrin.
