A stunning picture book about one little girl and her orangutan friend, based on the Greenpeace film that became a viral sensation. When a little girl discovers a mischievous orangutan on the loose in her bedroom, she can’t understand why it keeps shouting OOO! at her shampoo and her chocolate. But when Rang-tan explains that there are humans running wild in her rainforest, burning down trees so they can grow palm oil to put in products, the little girl knows what she has to do: help save the orangutans! Extra pages at the back include information about orangutans and palm oil plus exciting ideas about how young readers can make a difference.
