Dive beneath the sea with an animal crew in this bright and bouncy underwater adventure. Machine-mad pre-schoolers will love learning about life on a submarine - from how it works to where the crew sleep. An audio CD attached to the inside back cover allows children to listen to the story and follow along with page turn cues. This popular picture book series makes learning about vehicles more fun than ever before. Each of the "Amazing Machines" picture books features lively rhyming text and bold, bright pictures of fun animal characters. A picture dictionary at the back of every book helps build vocabulary. Four "Amazing Machines" with CD were published in June 2007, and a further six titles will be published in October 2007.
