"The Berkley Gulp! Nightcrawler blends the scent, appearance, and taste of a real nightcrawler with the action, shape, and durability of a soft plastic. It can be rigged like other soft plastics and hooked on a spinner harness, light jig, weightless hook or Lindy rig for hours of action. The Gulp! 6"" Nightcrawler is the result of more than two decades of research and field-testing; its water-soluble natural ingredients release over 400 times the fish-attracting scent that standard plastic baits do, creating a scent trail so intense that fish cannot resist it. 12 baits per 1.8-oz. jar. Live bait attraction Plastic worm fishability Rig like other soft plastics"
