This title is part of Pearson's Bug Club - the first whole-school reading programme that joins books with an online reading world to teach today's children to read. In this Purple-B level Pete's Pet Shop book: The wilful princess wants a unicorn, so her father, the king, asks Pete to find one. Pete advertises but is not fooled by a trickster who tries to sell him a donkey. Sally takes her unicorn to the princess. The unicorn is not impressed with the princess’s tantrums, so Sally teaches her how to look after it and how to become a real friend.
