Rainbow Butt Monkey (3.5e Monster)

"Bert...am I imagining things...or are there lights shining from that monkeys nether regions?"

"Best we not think too much about it and just keep moving Abner..."

Rainbow Butt Monkeys appear to be normal Mandrills, however their nether regions are a reflective mother of pearl color. At will they can cause them to sparkle with all the colors of the rainbow, fascinating potential victims while their brother monkeys sneak up on them from behind. No one's sure if the effect is magical or people just tend to stare thinking "wtf?". Currently Sages have no explanation for their existence, as they one day simply began overrunning the nearby savannahs.
