The thieves are wearing a mask and a hat. They seem so weirdo. Three owls tell uncle owl immediately but the thieves leave the house before uncle owl arrives.
They begin to follow footsteps of the theives. Then they find the place where they are hidden and start watching when they catch them, they understand that the thieves are their parents. It`s a birthday joke and the stolen things are their birthday gifts. It is funniest birthday they have ever lived.
