I don't think there is such an animal. I remember a discussion on here couple three years ago about that. Someone had tried to get one of the mold makers to build one. Think the answer was with those ribs it was so complicated to engineer and would be so expensive they didn't want to fool with it. Then I also don't know if it has some kind of trade mark like road runner that would keep people from building it. There is a similar bait out there but a lot larger and flappers on the side. These wer originally designed as a flipping bait for bass then got down sized into a crappie bait.
