Animal Haven is a temporary home for all sorts of Australian wildlife, although there are a few permanent residents as well, like Oscar the owl, Fur Bag the possum, Cinnamon the koala and Alice the labrador. Meg and Mike live there, too, and they work so hard to help their parents rescue and look after the animals that the locals at Jeff's Creek have nicknamed them the Aussie Angels.
This time the Aussie Angels find a black dog in the forest, and they're concerned about the safety of the wallabies there. But instead of annoying the wallabies, he seems to think he is one! When he runs he tries to leap along.
Mike and Meg take him back to Animal Haven, and Alice the labrador is pleased to see him. But Elsie the emu is certainly not impressed. And when Wanda the wallaby hops in for one of her visits, lots of surprising things happen.
