Could you tie a little marabou tail, then if the cut in the bead is wide enough to slip it over the hook and tail. But instead of have the slit in the direction you have it, put it facing the other way. A few drops of super glue should hold it all together. Then push some cactus chenille in the slit to hang down like legs held in place by more glue. Or use bucktail instead of marabou and let it extend forward to look as feelers. As above use something in the slit to look like legs and Voila, a shrimp .
