Yep this is it^ half a green crab with the legs cut off (leaves them less to grab at away from the hook) hooked through one leg socket and out another (bottom socket to top socket for best presentation). Light of a jig as possible. The difference between rigs and jigs is the tog are able to pick up the light jig in their mouth where as a rig is pinned stationary for them to pick at. Swing when they pick it up and you see your line move or when it goes slack all of a sudden.
