I am 9 years old here is my opinion of this book.
This story is about an adventurous Guinea Pig called Olga da Polga.
Olga is bought by Karen Sawdust who takes her home in a motor car, which is a big adventure for a guinea pig. When they get home she meets Noel the cat. Olga tries to impress Noel with increasingly boastful stories. She meets new friends Graham the Tortoise and Fangio the hedgehog. Fangio encourages her to escape from her run, but the outside world is not what she expected and she is really grateful when the Sawdust family find her, cold and injured, and take her home. She makes an amazing recovery after watching the Dance of the Sugar Plum Fairy on TV!
The story ends on Christmas day when Olga receives a present from Father Christmas.
I really enjoyed this story because,Michael Bond has made the animal characters come to life.
