One very brief shot stuck in my mind as a child. In the episode "Wizard of Stone Mountain" Ram Man's feet are burnt by the Spirit of Evil causing him to leap into the air. The Filmation artists create a very nice, very brief comical moment where we see that Ram Man's legs really are just giant springs! I first saw this episode in 1984 and did not see it again until 1996; yet this shot always stuck in my mind!
