Scary Plugins for halloween...?

So... like everyone else Im looking to do something cool for halloween for our server. I set up a haunted house and while it is hard to make minecraft "scary" I think with the right plugins you could do some cool tricks

I have special effects with blindness which works really good. I was wondering if there were any other plugins though that I could use with a haunted house. I couldn't keep up with plugins these past few months due to other things going on in my life right now so it would really help if anyone knows of any plugins They can be obscure if you want, just anything that you think might fit in!

 

HalloweenScares? its REALLY good!

 

I guess it's kinda late for halloween now. You had specialeffects you said. Just a thank you for that. you could scare your players with /se player.balrog or mines i guess haven't thought of the scary part for the plugin yet. Sheers //CevinWa
