Flash (Voodoo/crab fleck) To match tail (few strands)
Flex Hackle / Life Flex Wrap To match hackle (1 length (body))

How to tie it
Start thread mid-shank and lash a pair of large lead dumbbell eyes on TOP of the shank about a third back from the eye, mounting them up top flips the hook to ride point-up and swim weedless over oyster and grass.
At the bend tie in a wick-shaped clump of craft fur about one shank long, tapering the tips to a point.
Lay a few strands of flash over the tail, kept sparse.
Tie in a length of Flex Hackle at the tail base and palmer it forward to the eyes in touching turns, building a dense, water-pushing crab body; tie off behind the eyes.
Cross the thread to the far side of the eyes and dub or bunch Ice Dub around the shank forward of the eyes, figure-8ing around them for the head.
Brush the Ice Dub out well so it flares into a buggy head, whip finish at the eye, and cement.
