Snooping through the game’s files, I found the titles for most of the Halloween Items (and/or items that are yet to be added)!
Broomstick
Nasty Cleaver
Evil Cauldron
Eyeball
Floating Book Pile
Floating Candle
Floating Candlestick
Forgotten Remains
Jack-O-Lantern
Lantern
Mini Ghost Pet
Nightmare Crab
Skull Candle
Skull Mask
Spooky Gun
Quarter (probably has nothing to do with this update)
Throwable Cleaver
Throwable Knife
Tin Can (probably has nothing to do with this update)
Thoughts?
EDIT: really fluffed this post up, fixed that!
