This looks chartreuse with black specs to me. Woods and Water has a Chartreuse Pepper chenille, Skip has also has something similar if I remember right. Most have more black in them then the bait you referenced. Might be good to just get a chartreuse chenille and then put a black sharpie marker dot in some places.
