Today is Tía's birthday! Cecilia wants to surprise her great-aunt with a very special present. But what could it be? Could it be Tía's favorite mixing bowl that she and Cecilia used to make delicious bizcochos? Could it be a ball like the one Tía played with as a little girl in Mexico? With the help of her cat, Chica, Cecilia plants the perfect surprise. And Tía has a very special surprise for Cecilia, too!
