Pocoyo finds a four-leaf clover and is sure it is a good luck charm. Pato decides to have an amulet too: a horseshoe. They both believe that their amulet is better than the other's and start an absurd "battle of good luck"... without noticing the problems they cause to their friends. Finally Elly comes to the rescue: Pocoyo and Pato understand that there is no better luck than to have a good friend.
