There was a line of toys in the late 80s to early 90s that consisted of a small base containing a wind-up mechanism. Usually a small figure was put in the center and the whole top would revolve as the mechanism wound down. If the player did not complete the task before this happened, the figure would pop up like in the game "Perfection". One toy involved building an egg around a small green monster and another consisted of a mad scientist surrounded by small disks that one would have to grab with a magnetic arm. Does anyome remember the name of this line?

Thanks,
