A long time ago, some animals looked different to the way they look now. Kangaroos had no tails and wombats had high, round heads.
Mirram the Kangaroo and Warreen the Wombat were good friends. They lived together in a hut that Warreen had built from tree bark. They liked being with each other, but Mirram liked to sleep outside at night and he made fun of Warreen who always wanted to sleep inside.
"Come, Warreen, sleep outside with me" said Mirram. "It's much better to look up at the stars at night and listen to the fresh wind in the trees."
"It's too cold outside" snuffled Warreen, "and sometimes it rains. I might get wet! I like sleeping in my hut with a nice fire to keep me warm."
Mirram the Kangaroo would not accept this. "Your bark hut is dark and smelly. It is much better to sleep out in the clean air under the bright stars!"
