This is going to be the MOST SIMPLE combiner ever. We are keeping it Playskool. The cars are only going to plug onto Hauler Bots robot mode. The STUNT-Y-CONS are comming ! They will play together as MEANIE-SORE . We have already worked out the VERY simple childlike combining process. This is suppose to be cute. not complex Motor Master = MOTOR COACH If no one thinks its name is cute enough, changing his name was hard, and a motor coach is a semi like truck that can carry a car. Which this toy can do in its bed. Drag Strip = ROAD TRIP I did not use the Playskool F1 car because it is bigger than the others. I never liked that mode for this group anyway, and this fits the closest for a convertible. Break Down = SLOW DOWN Wild Rider = SUNDAY DRIVER Dead End = REAR END We used this mold because of its whale tail to pay respect to the Porsche 928. This is the only figure being modded to sand down the roof lip, and replace the bulky front end. We did not want to use any of the same lil' bots for these guys. We had to use two of the same front ends though.
