A large grey elephant is following Olive’s father around. It leaves with him for work and is still trailing behind him when he comes home again, keeping him heavy and sad. Every day, Olive wishes it would go. When she falls from a tree and gets a concussion, Olive awakes to see a grey tortoise walking behind her grandad. With the help of her friend Arthur she manages to get rid of it, and the three decide to try to chase the elephant away too.
