A group of children find a sloth snoring away in a tree in their garden. Not knowing what it is, they set out to find out. While the two older children dream up increasingly outrageous possibilities, from an astronaut to a pirate, to a space creature, the youngest little girl investigates books and a globe and discovers what it really is and where it lives. But how can the children help the sloth to get home if it won't wake up?
