RGB Zac

I don't have anything to link or show, but anyone with a RGB keyboard or mouse will know what I mean. Those that don't picture this, Zac's (skin?) slowly cycles though all the color's of the rainbow, this applies to his chunks as well. Simple and nice right? No need for fancy work with the model just color work. Or they could release just some recolors for a low low price, it would be nice for Zac to get something since it's been almost 2 years since his release.
