nce upon a time, there lived a lizard who could not climb.All animals decided to climb to hunt for food but the lizard was afraid. One of the birds helped lizard to get up to the tree. After gettinf some fruits from the tree, the lizard did not know how to climb down so he lifted himself up and threw himself down. When the other animals saw him, they laughed. The lizard praised himself by nodding his head. This is why the lizard always nods.
