Brazilian boy Felipe doesn't have a soccer ball. So, when it's his turn to take one to school, he uses a little bit of creativity… and a few socks. Felipe is the sock thief, but finding socks is not that easy and the neighborhood pets make it even harder. "Au, au, au!" a dog barks in Portuguese. Felipe wonders if he'll play soccer with his friends today or if he will be caught by a tattle-tale parrot? Along the way, Felipe leaves delicious mangoes in exchange for the socks he steals. After he swipes each pair, he twists and turns them into an ever-growing soccer ball. At the end of the day, he returns each pair of socks with a note to say thank you.
