Building on the proven attraction of the original Yum Dinger, the Yum Thumpin’ Dinger is fitted with a hard-pounding backside that allows it to pull double duty as a regular worm. Molded with a hard U-shaped tail, the Yum Thumpin’ Dinger produces a panicky swimming action that outputs plenty of vibration and water movement. Offered in a number of classic colors, the Yum Thumpin Dinger creates a pulsating action that takes the attraction to a whole new level. Length Quantity 6" 10
