River2Sea Whopper Plopper 90 is a 3 1/2 inch, 3/8 ounce topwater lure with a rotating rear single propeller. The culmination of many years of fine-tuning a specific style of lure, they are precisely molded and every single one comes out of the box with the perfect tail size and angle to make a sound that simply drives fish crazy. Its tail is made of super-tough plastic that flexes right back into place whether it gets chomped on or gets cast into a bridge piling.

The River2Sea Larry Dahlberg Whopper Plopper 90 is "roll-resistant" and works well at a variety of speeds. Sound experiments have suggested that even at constant speeds the tail kicks out sounds that vary as much as an octave in pitch as opposed to the more monotone metal tails.
