It's a big day in Pixieville: all the citizens get ready for the Yearly Yodel Festival. Tune has big chances to win the trophy, but she caught a bad cough. Caramel has the right solution for her: with her special mints, in fact, she'll be able to treat her voice. When she has to sing on stage, Tune uses the mints and she coughs one last time… she seems to be fine now, but with her last coughing she creates a magic cloud that infect all Pixieville's citizens, making them dumb!
