Get some wiggle eyes from Michaels, Hobby lobby etc. 2.5mm to and up depending on jig size. If the jig has lead eyes flatten them and you just glue the eyes on. You can make them on any type head you want if you can get a flat spot on it, ball heads squeeze with pliers till flat, paint and glue them on.

Saw some 2 packs on ebay and a search on Zeta bait company, Mr. Wobbley in foley, Alabama didn't come up with much. Maybe someone else has a better search idea.
