Wizards of Waverly Place Episode 1.20 Quinceanera

The family prepares for Alex's quinceanera, a traditional celebration to mark her 15th birthday, but she doesn't want to wear the customary frilly ball gown and casts a spell to swap bodies with her mother, who never had a quinceanera of her own. Also, joining in the party is Grandma Magdalena, who tries to teach the boys how to salsa dance. But she soon forgets to teach the boys so they use the Body Switching spell with the dance instructors to make it look like they had learned the dance. In the end, Alex does make it back to her body before sundown, and Grandma Magdalena finds the Magic Lair but thinks it is a wrestling room.
