Circus Halloween Adventure

[Ninjattack]

My players just finished a plot line, so I decided to give them a quick themed adventure. And hey, Monday is Halloween so why not do something in the spirit of that?

I tossed around a few ideas and the most popular one was my idea of a 'Killer Circus/Carnival'. I was wondering if anyone knew of some adventures similar to that, or if anyone knew of some cool monsters and loot that would work for an adventure like this? I'm also curious if anyone would know how to make some sort of killer clown monster, if one doesn't already exist.

Not sure if you still need this, but here I am anyway! I don't know of any adventures written like this, but you could use the Red Jester monster in Pathfinder. I'd add a link if I could

There's Carnival of tears (http://paizo.com/products/btpy80op?GameMastery-Module-E1-Carnival-of-Tears) a dnd module by paizo which you could raid for idea.

Villain Codex has a chapter of evil carnival statblocks, and Bogeymen (http://paizo.com/pathfinderRPG/prd/bestiary3/bogeyman.html) make good monster clowns.
