Toad Thumper Tremor Shake Finesse Worm - The Toad Thumper Lure Co. Tremor Shake was designed to be the most versatile finesse worm ever created made with a custom, soft plastic formula to add durability as well as allowing the bait to sink and shimmy perfectly on the fall. The Tremor Shake was designed with an air pocket in the tail to make sure the bait always stands up off the bottom while the worm is at rest. This worm uniquely excels at both wacky and shakey-head rigging as well as drop shot. The Tremor Shake is infused with proprietary Bio-tonic scent.
