You may not know this but Berkley has a simular product(s) that walk, and smell like food / taste to fish. I will be speaking about these products at my seminar on the 7th. for Walleye Searchers in Rochester.
This photo shows the Berkley Bungee Worm “walking”. It naturally recoils when it comes to rest on the bottom, just like a real night crawler! They added Bio-Salt to the flavor, which simulates the salt content of live prey fish. This is much different than ordinary table salt that is found in other baits. Hey, if it tastes better… they’ll hold it longer… or just eat it!
You should not have to sell the farm to pay for these either. Hawger
