When I received my Lift N' Load Quarry in the mail, I noticed on the back of the packaging that there appeared to be one more GeoTrax new release that wasn't being talked about yet. It is a new Cement Mixer Truck.
This appears similar to the garbage truck, police car and ambulance released earlier this year. A push vehicle that makes different cement mixer truck sounds at the push of a button. I have only seen these for sale on eBay so far.
