  • Patent number: 6408565
    Abstract: A fish bait device has a substantially three-dimensional front portion having the appearance of at least the head of a given animal, and a substantially three-dimensional rear portion having the appearance of at least the tail or abdomen of the given animal. The front portion is pivotally connected to the rear portion, and together, the front and rear portions form an integral fish bait device which exhibits a realistic appearance and movement of an actual live bait. The front portion generally has a duct that directs a stream of liquid medium toward a deflecting surface on the rear portion. The deflecting surface deflects the stream causing the front and rear portions to swivel, or wiggle, relative to one another in a realistic movement of an actual live bait.
