@Mitz was actually the one who turned me on to those frogs.
We were fishing a club tourney and we started the morning off about 50 yards from each other on the same point with some submerged shallow weeds.
I wasn't getting hit at all, but every few minutes I would hear a blowup over near his boat. After hearing this at least a half dozen times, I hollered over and asked him what the heck he was doing to get that kind of action. He motioned me to come over, and being the nice guy that he is, he proceeded to show me what he was throwing and then handed me a bag of them, along with a pack of hooks.
I tied one on and used them for the rest of the day, going on to catch a few bass and a monster Northern Pike on them.
The funny twist to this story is that I went on to take second place in the tourney, ahead of Mitz. And all of my fish that day were caught on that Ribbit frog
