The unique hump-backed shape of Little Cleo results in a seductive, wiggling action as the lure is drawn through the water. The illusion created is one of a fat baitfish, acting in an erratic, confused manner. This odd behavior triggers the predatory nature of the gamefish, who strike out of curiosity and anger, as well as hunger. This three-way appeal hooks them every time, and explains Little Cleo's fantastic success - it's famous countrywide as the one lure that takes all gamefish.
