Maria catches Rosita trying to use her wings to fly like the birds. Rosita thinks that since everyone in her family has wings, she should be able to fly. But when Maria asks if any of Rosita's family members actually can fly, she realizes that none of them can. Rosita is upset about not being able to fly, so Maria takes her to someone who will understand how she feels ... someone who happens to be a big bird. (thetvdb.com)
