Trick or Treat Month returns... and this time it's personal! Join us for another month of spooky themes and special surprise guest apparitions! Try not to get too scared!

And so we close the ancient, flesh-bound spell book on another Trick or Treat Month... but we're going out on top, baby! Alexis Nikole Nelson has appeared, as if by magic, to lead us into the deep, dark woods and point out all the slimy, sticky, gross stuff on the ground that she says we can eat. I guess I trust her!
