Mimí loves going to Puerto Rico every year with her family to celebrate Christmas. She especially looks forward to her annual parranda, the Puerto Rican version of Christmas caroling. But when she learns that her family won't be able to go this year, Mimí is so sad that she stays home in bed on the day of her class' holiday party. Just as Mimí is falling asleep, though, she hears the unmistakable sounds of musical instruments. Could it be that she'll get her parranda after all?
