i actually have a lure put out by Chuck Woolery that has the string type device you were talking abouth the frog having. It's a bass colored lure that swims for a few seconds after it hits the water and the string winds back in. It does swim. Maybe something with that type of coil spring system connected to a paddle wheel of sorts to make the lure back up? just a thought.
I'm not even sure who is joking and who is serious anymore. I am sure though that Bob Barker wouldn't have approved of the chick-lure.
