Donald Duck and José Carioca hop inside a book and take a train to Bahia. When they get there, they hear a someone singing. José says it's Yaya, a beautiful woman who sells cookies. Sure enough, Yaya appears with a tray of cookies and starts singing the song "Os Quindins de Yaya". Donald falls in love with her and repeatedly tries to get a kiss from her, but is interrupted by a bunch of men who also flirt with Yaya. Eventually, some other women appear and the men (as well as José) leave Yaya behind, much to her disappointment. Donald shows up and hands her a bouquet of flowers, which cheers her up and she gives a Donald a kiss (causing him to pass out and hallucinate) before leaving to join the others. The group continue dancing and Yaya uses magic to make various objects come to life and dance (Tables, houses, buildings and even the Moon). Finally, the party ends and Donald and José leave the book. She is not seen again after Donald and José leave the book.
Yaya is a very rare character who makes appearances at special events at Disneyland Paris.
