Pocoyo notices that something is casting a shadow over him. It's a cloud. And wherever Pocoyo goes, the cloud follows. This annoys Pocoyo. He goes to Pato the yellow duck for help. But the cloud annoys Pato by following him around instead. Pocoyo and Pato both try to escape the cloud, but wherever they go, the cloud goes, too. Finally, Pocoyo angrily orders the cloud to go away. Is that rain pouring from the cloud? No, those drops are tears. The cloud is crying because his feelings are hurt. Pocoyo and Pato discover that the cloud just wants a friend.
