this was an incredible machine, which turned plastic cubes, or squares, into various prehistoric animals and some monsters, among other things. go here for the complete story on how everything worked (except covering up burns so your parents wouldn't take the dangerous thing away from you).
I would have liked more dinosaurs. ditch the bugs, the skeletons (fish and man), the robot and the other man-like beings and add more dinosaurs. keep the snake and the octopus.
