THE Monster MASH!
All these guys are put in the thick woods of canada, they cannot leave the 1,000 square foot area...the monsters are...
Werewolf (your best version)
Frankenstine (your best version)
Dracula
Mummy (your best version)
Jason
Freddy
Mike myers (not the funny guy)
You could add any monster you like to the mix, as long as they are not over 11 feet tall (no godzilla's, king kongs, ect.)
Only one monster comes out alive, they all must engage in physical combat with in the first hour or they are disqualified...
Who is the king of all monsters, winner gets to go trick or treating in hollywood...
