The Spooky Party has some new stuff!
First of all, in the Spooky Party den shop, you can get a Ghost Winder! (Window, it's from iCarly: "Ya Spencer open up that Winder! She died, though, she fell outta winder hehe. Just kidding she had a heart attack...")
Also, there is a secret place where you can buy a pet Bat!
First, go upstairs to where you would buy clothes. You'll see a Candelabra. The wallpaper has all phantoms, except for one spot above the Candelabra where there is a faint bat. Click it to buy a pet bat! (Members only)
Also, I found this snake glitch here, but it doesn't really have anything to do with the party itself.
It's like, half of a snake. I though it was an evil piece of grass or something...
