This adventurous picture book is the tenth title in this critically acclaimed series for toddlers by the poet Tony Mitton and the illustrator Ant Parker. Young readers climb aboard a super submarine with Mouse, Rabbit, and Bird and learn what submarines do, how they do it, what makes them go down, and how they come back up again. Appealing artwork complements the lively rhyming text, and there is a helpful illustrated glossary of technical words at the end to help build vocabulary and identify what"s what in super submarines!
