This is what he told me.
The bottom was shaped like a boat, a v shape hard body, but the top had a profile of a frog, soft plastic.
The proto type resembled a bull frog.
He also told me that he caught 10-14 lb bass at night testing it out as he did,nt want anybody knowing about his bait.
But he told me also that he down sized the bait for other fishing conditions where the frogs are smaller.
I beleive the person who told me as he has nothing to gain from what he told me.
We were just fishing and frogs came up in the conversation and he told me about it.
