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 Yellow-B level Zip and Zap book: Zip and Zap travel to Earth, and meet two children, Liz and Sam. They play happily in the snow together all day. Zip and Zap take a snowman home with them, thinking it’s Sam. When it melts, they think it’s because Sam didn’t like them – but then they see Liz and Sam waving to them from Earth!
