The round battle arena is waiting for you and you must go to it fully armed in a car specially prepared for the fight in Merge Car 3D. Therefore, you must first make a magical connection. Select an animal, bird or creature and it will be connected to the car, giving it additional properties. For example, you have chosen a turtle, which means that your car will leave behind mines in the form of a turtle shell. Bat to make the car run at supersonic speed, and Siren Head to make scary sounds, and so on. Access to the rest of the creatures will open as you move through the levels in Merge Car 3D.
