One night, blasts of wind lashed the kangaroo with raindrops that felt like icy needles. Mirram was so wet and cold, he couldn't take it any longer. He struggled onto his hind legs and, blown by the wind, hopped slowly towards the bark hut.
"It is me!" screamed Mirram, banging on the door. "Now, let me in!"
"No!" yelled Wombat. "There isn't enough room."
Mirram's teeth were chattering. He became very angry and pushed hard at the door until it opened. "I'm inside now - and you aren't big enough to throw me out!"
"H'mmph" snorted Warreen. "Well, sleep over there - in the corner. You're all wet and I don't want cold rainwater dripping on me." Wombat stretched out near the fire again and went back to sleep.
Mirram lay down in the corner, but there was a hole in the wall of the hut and the wind and rain came in. He couldn't dry himself or get warm. The fire went out, but Warreen didn't notice. He snored as he slept and laughed every now and again, enjoying a nice dream. This made Mirram more angry.
In the morning his body was stiff and sore. He hobbled outside and picked up a large rock. When he came back, Warreen was stretching and yawning as he woke up. Mirram dropped the rock on Warreen's head, flattening his forehead and making his nose curl around.
"This is for not helping me get warm and dry," said Mirram. "And from now on, you will always live in a damp hole. Your flattened forehead and cold home will remind you of last night."
After that, Warreen and Mirram didn't speak to each other or play together, and Warreen planned revenge.
He made a big spear and waited until Mirram was busy washing himself. Then he threw the spear with all his strength, and it hit the kangaroo at the base of his spine. Mirram yelled in pain and tried to pull the spear out, but it was stuck.
"From now on, that will be your long tail," yelled Warreen, "and you'll never have a home to live in!"
That is why wombats now have flat foreheads and live in dark, damp burrows underground, and why kangaroos have long tails and always sleep outside, under the stars.
