Meet Robbie. Robbie is a seal. He is Pingu’s best friend. Pingu and Robby like doing things together like snowboarding and scaring Pingu’s little sister. This book is short and sweet with lovely illustrations. Rating: I would rate this book 5/ 10 because it is up to standard and very good for young children; the words are easy to read, they are easy to understand and the words are repeated. It comes in a set and if you have all of the books in the set then on the spine there will be a full face of a penguin (each book has a part of a face).
