I once tried to convert an MS Slammer in to looking like a catfish. I felt like from the fish's perspective (looking up) the whiskers would be an important attribute of the lure - signifying 'catfish' to the fish.

So what I did was drill out a hole through the head and add whiskers. The material I used didn't move in a lifelike way, but I bet you could find something better that moved like catfish whiskers really moved. If you've ever watched small catfish feeding on insects or foam on the surface they tend to flare their whiskers out quite a bit.

I got to watch this at length on the Green River in Utah where tens of thousands of small channel cats would congregate in the eddies to feed. They move with a lazy head action and even the small ones have pretty good sized whiskers, kind of like puppy feet.

That's just some random food for thought :)
