Once the top of a Burrawang tree fell to the ground,,,
and the grassy top began to change. It became Grug.
Away he went to look for a place to live.
He went through the forest,
through the snow,
until he reached a green mountain.
There Grug found a deserted burrow.
He worked...and worked...to make a fireplace.
Then he made a bed of grass.
Grug's house was almost finished.
What else did he need?
A letterbox!
THE END
