In the Dreamtime, the Rainbow Serpent helped the world along with rain. At the beginning of time, the Rainbow Serpent awoke from its sleep and pushed through the Earth's crust. As it travelled over the empty land, it left behind deep tracks. The Rainbow Serpent called to the frogs to come out from beneath the earth. It tickled the frogs' bellies, and when they laughed, water poured out from their open mouths. The water filled the Rainbow Serpent's deep tracks, making rivers and lakes.
