    A long time ago, people were afraid to sail along Tulang Bawang River. A big crocodile lived there and would attack boats he saw. Not far from the river, there was a village. Aminah, a beautiful girl, and her parents lived there. One day her parents asked her to go to another village across the river. "Please be very careful, dear. If you see the crocodile near you, row your boat as fast as you can," said the mother. “I will, mom," Aminah promised. Aminah rowed her boat slowly. She did not want to make any noise. She did not want the crocodile to hear her.

    However, the big crocodile already saw her. The crocodile silently swam closer and turned the boat face down. Aminah was drowned. She was unconscious. When she was awake, she was inside a big cave. She stood up and looked around. She saw something shining in the dark. When she approached it, she found a lot of jewelries. She was very surprised. Suddenly she heard a voice. "You can take those jewelries. But you have to stay with me." The voice was from the crocodile. It was the same crocodile that attacked her in the river.

    “Don't be afraid. I'm not a real crocodile. I was a human. I was a pirate and always rob people's jewelries. A witch cursed me into a crocodile. And now I keep all the jewelries here inside the cave."

    "How do you go to the river?" asked Aminah.

    “There is a tunnel that connects the cave to the riverside," explained the crocodile. He accidently revealed his big secret.Aminah then pretended to agree to stay inside the cave. When the crocodile was sleeping, she took the jewelries and went to the tunnel.

    Finally, she arrived at the riverside and some villagers helped her. Aminah's parents were very happy, their daughter managed to be back home. They sold all the jewelries and gave the money to other villagers. Everybody was happy, they were not poor anymore.
