DisneyCarToys Frozen Elsa's kids go to Barbie's Gymnastics school. Using the Barbie Gymnastics Teacher set, Disney Frozen snow queen Elsa takes her kids to a gymnastics class taught by Barbie with a Chelsea doll as the main student. Elsa and Prince Felix's kids are Kelly dolls which are vintage 1990s Barbie Kelly dolls named Alex and Felicia. Felicia has fire powers unlike Elsa's ice and snow powers. Alex has no powers but seems to have a super power of being great at gymnastics. Chelsea gets jealous but Barbie is proud. Elsa's son tells Elsa in their Barbie Car that he does not want to take gymnastics lessons from Barbie but it's too late.
