Super Turtle

I was amazed to learn today that there was a cartoon character in the 1960s named Super Turtle.  There's an interesting story about Super Turtle and Supermam here on Big Shiny Robot.  It seems plausible that Superman overshadowed his terrapin counterpart making him frustrated, selfish, and looking for fame and gratitude.  But, you'll just have to click on over to see if that scenario is actually true.  I can't believe Super Turtle appeared in so many scenes and I never knew he existed!
