How to tie it
Start the thread; add a strand of underbody flash/dub if used.
Cut a thin strip of 2mm purple foam about 1.5x hook length and one gap wide; tie it in at the rear and segment it forward with thread locks to form a small foam body ending near the eye.
Figure-8 in barred purple/black rubber legs at the mid-body so they splay out and flop.
Tie in a short poly-yarn wing/indicator post for visibility.
Fold the front foam to form a small head, tie off, whip finish; trim legs to length.
