Search Bukkit Plugin, Which makes mobs shine

Hey guys. The question is already in the title but I have a simple question. Namely, for cosmetic purposes, I primarily need a plugin that lights up mobs such as fire, glowstone, spiders eyes, etc. As I want to upgrade bats to fireflies, because when they shine, they would be invaluable cosmetic to perfect sceneries , Every suggestion is a help. Thank you in advance.
