Pumpkin Pummeler Trap

It takes one seriously evil pumpkin seed to grow a squash so steeped in malevolence, so genuinely nasty that it will sacrifice its brothers and sisters on the vine to smash random passersby... but hey, it makes a great trap mechanism. Mice come in, expecting a festive treat, (and maybe a guy dressed up as a scarecrow jumping out of the bushes), and instead, they come face to face with a real Halloween horror, complete with monster teeth!
