Acacia was learning more and more about the amazing animals and plants that lived in Bungabbee Forest. But she was also learning that homes were in short supply.

So many of the animals needed to live in tree hollows - holes in trees that take hundreds of years to form.

The Brushtail Possums were nocturnal meaning they slept in the day and came out at night. They needed big hollows. They got grumpy if anyone even looked into their homes.
