The black sets can be made into bumper cars in this way, also.

                                      Claw wags his tail, moves around objects, and grabs things.
 

                     Green Man walks.                                    Bumper car went to "Mars."

                    The Easter basket was filled with eggs by "flinging" them in.

           This tractor like car "walks" with a different gate when one set of locked wheels is rotated 90 degrees.
 

Mars Box with Red Rover

 
                                                           One Robot gathers balls and another Robot moves in and takes pictures.
 

Merry - go - round has a blur of light.
