'In Wombat's Friend, the wombat we met in Wombat's Secret is told she's strange because of her friendship with the wallaby. She must work out what is important to her -- the opinions of others, or her friendship. There are three species of wombat -- the common wombat (the main character in this story and the wombat who falls asleep are both common wombats), the southern hairy-nosed wombat (like the wombat who calls her strange), and the rare northern hairy-nosed wombat.'
