ZOMBIE MONKEY HALLOWEEN

There is neither a funnier nor friendlier living animal than the free and silly monkey, all inquisitive and full of life. But once a monkey is cut loose from the mortal coil, all that goes down the shitter, my friend. A sick and twisted, angry and violent creature emerges once the specter of death takes a monkey from life. Gone is that lovable, curious monkey. It is replaced by a mean motherfucker that wants nothing more than to use its opposable thumb to grasp a big ol' crowbar and start some shit-- mainly with humans, because we think we're better than them! Putting them in zoos and shit! Making them dress up in funny clown costumes and juggle! Sending them in space because we're too pussy to try it first!
Them monkeys are full of righteous rage in death, yo!
It's upsetting, I know. This is why any witches, warlocks, or mad scientists worth their volume in unleaded gasoline wouldn't resurrect a dead monkey in some bizarre ritual, experiment, or what-have-you, no matter how evil the scheme. Too damned dangerous.
But, one night, one fucked up Halloween night, for reasons unknown, monkeys that had left our plane of existence rose from their graves and walked amongst the living again! ZOMBIE MONKEYS! And you bet your ass they grabbed crowbars and beat the living shit out of everyone and everything in their wake!
DAMN YOU, ZOMBIE MONKEYS! GO BACK TO HELL WHERE YOU BELONG!!!
