Abstract: A fishing lure (20) has a body structure (22) with hooks (24) attached thereto. A windup mechanism (80) includes a spool (58) and a spring (90) operating in conjunction with the spool to store energy therein. Propulsion structures, such as legs or fins (26, 28, 224, 226), extend externally from the body for movement upon operation of the windup mechanism. A shaft (60) extends through the spool and windup mechanism and is rotatively secured to the body. A drive train structure (120) is driven by the spring to provide an oscillating movement to the legs or fins.
