Celebrating the twentieth anniversary, this is the story of Mothball, one of the world's most famous wombats - and where it all began. She is small. She is scared. She is lost. She is a baby wombat who needs a home. She is Mothball, a wombat destined to become famous. This is the (almost) true story of one small wombat who learnt how to train her humans - and inspired the internationally best-selling picture book Diary of a Wombat by Jackie French and Bruce Whatley.
