When two little aliens in a passing rocket spot the most exciting thing ever, they can't wait to land on Earth to investigate. They've discovered ...a playground! It is full of fun-looking things like a seesaw, a sandpit and even an ice-cream kiosk. The thing is, the aliens have never been to a playground before, so they don't know how anything works. Hilarious confusion soon ensues until new friends show them how to have fun. Sam tells this charming and funny tale with her well-renowned quirky sense of humour. Children will delight in knowing what the two little alien friends are getting wrong on each page and, naturally, there's a very happy ending extolling the virtues of friendship and helping others.
