Climb onboard a fire engine inthis action-packed addition to the Peep Inside how it works series. Nee naw, nee naw! The fire engine is here to save the day. Peep into the cab, roll out the hoses and slide out the ladder to find out how it works. Truck-obsessed toddlers will love all the details to spot, flaps to lift and holes to peep through. An exciting introduction to some of the people who help us.
