The Clone frog is made w resin plastic. I made a simple silicone mold of one using Alumilite products or see Larry Dahlberg videos. I molded a few but switched gears ( it didnt seem realistic enough and the legs were too short and unrealistic also) and use hollow body and soft plastic Horny Toads now . Anyone can make a frog seem great in a video in the right pond in Florida. This lure caught me , the fisherman, well before any fish
