Halloween can be expressed as a mathematical equation. Much like the Powerpuff Girls, Halloween is made up of three parts (plus an accidentally-added extra ingredient to the concoction — Chemical X). First, there are the costumes — not much of a holiday without pretending to be courageous heroes and nefarious villains! Next, of course, there’s the candy. Delicious. Sweet. Deliciously sweet. Finally, there are the spooky decorations, without which Halloween would be just another cosplay party where we binge on chocolate.
