Children will delight in guessing their way through this interactive mystery. In this companion to 'Dig In' follow these construction mice as they twist and turn, lift and lower, pump and bob in a showcase of construction vehicles with moveable parts. With up close construction site illustrations, the purpose of their work is not revealed until the very end when the filthy workers go to take an enormous bubble bath that they have finally completed. It's favourite vehicles meets bath time routine in this novelty board book with interactive mechanisms.
