There are many electronic voice changing helmets on the market, but few are as menacing as this Judoon helmet from the “Doctor Who” series. Interestingly, the Judoon kind of sounds like the Cookie Monster, so it’s really like having two costumes in one. Just wear a blue shirt and pants with the helmet and go around trick-or-treating with an empty bag of Chips Ahoy shouting “ME WANT COOKIE!” every time someone opens the door. So your Cookie Judoon costume will end up being both frightening and goofy — which equals just plain creepy. $29.99 – Entertainment Earth via Fashionably Geek
