The go-to tool for Halloween Horror Movie fancy dress.
If your planning a walk in the woods, be sure to take your trusty Chainsaw to guard against Zombies. Or maybe your a Crazed Hillbilly keeping those pesky college spring breakers away from your Moon Shine.
Happily this inflatable chainsaw is more likely to tickle than actually sever limbs so you'll need to make your own revving sounds. People will probably still scream though.
