Whether basking in the moonlight, enjoying the summer breeze, or listening to the pitter patter of raindrops, the Possum is in love with life. Always wearing a cheerful smile on his face. Especially as he hangs upside down from his favourite tree branch. But when one day Katrina, a little girl from the city, discovers him hanging upside down in the forest she mistakes his upside down smile for a sad frown and decides to bring him to the city to show this silly little Possum how to be happy. In this re-imagining of the classic book, the Possum embarks on an adventure to see all that the big city has to offer. But maybe it's not the Possum who needs to learn where happiness lies.
