Poly yarn Fluorescent orange or pink poly yarn (small tuft for post)
How to tie it
Cut a foam strip about a hook-gap wide and tie it in at the bend, leaving a tag that forms the rear gaster bump.
Bind the foam down to the waist at mid-shank, pull the front section forward, and cinch it to create a distinct pinched waist between two foam segments.
At the waist, figure-8 in a strand or two of rubber legs, one splayed to each side.
Tie in a short upright fluorescent poly post at the waist and trim to about a hook-gap tall.
Pull the remaining foam forward to form the front head bump and bind it just behind the eye.
Whip finish under the foam head and add a drop of cement.
