Once upon a time, there is a hungry lizard. He lives in a big garden. He sees a fly. The fly is in a glass box. The lizard is very hungry. He wants to eat the fly. But the glass box is closed. The lizard thinks and thinks. He has an idea. He moves a rock. He puts the rock near the glass box. He climbs on the rock. He is now on top of the glass box. He pushes the lid with his nose. The lid moves! The fly sees the lizard. The fly is scared. But the fly has an idea too. The fly waits. When the lid is open, the fly flies away fast. The lizard looks at the fly. He is sad. But he is not angry. He is smart. He waits for the next fly.
