These plastic squid lures first appeared in the 1970's and instantly became a popular fish catcher. They soon acquired the "Muppet" nickname which has stuck ever since.
Despite all the changes in tackle in the intervening years Muppets are still a good fish attractor proving particularly effective for cod and pollack.
5'' Muppets are the most popular size and work very well when used above a baited hook or when added to the treble hook on a pirk. The lumi are particularly effective in deep water.
