Long ago in the Dreamtime, Tiddalik, the largest frog ever known, awoke one morning with a huge thirst. He started to drink and drank until there was no fresh water left in the world. Soon creatures everywhere were dying and trees were wilting because of the lack of moisture.
All the animals pondered about their terrible plight until a wise old wombat suggested that if Tiddalik could be made to laugh then maybe all the water would flow out of his mouth. This was a good idea the animals agreed.
The animals gathered by Tiddalik's resting place and tried for a long time to make him laugh, but it was in vain. The kookaburra told his funniest story, the kangaroo jumped over the emu and the lizard waddled up and down on two legs making his stomach stick out but Tiddalik was not amused.
Then when the animals were in despair, Nabunum the eel who was driven from his favourite creek by the drought slid up to the unresponsive frog and began to dance. As the dance got faster Nabunum wriggled and twisted himself into all sorts of knots and shapes to the amusement of Tiddalik. Tiddalik's eyes lit up and burst out laughing. As he laughed the water gushed out from his mouth and flowed away to replenish the lakes, swamps and rivers again.
