A tremor has been reported in cemeteries all over the globe. Zombies are waking up everywhere, spitting cobwebs from their mouth and scratching their dry eyes, cursing the lack of eye drops. Dry eyes, however, will be the least of their worries in a few hours, for hunger will consume them. And akin to billions of Gollums, they'll wander the lands in search of grey and white matter, mercilessly attacking any unprotected soul.
We have decided that nothing less than the Death Star shall protect you from the zombie hordes. (I already checked and none of the zombies are named Luke, so your pumpkin's thermal exhaust port is safe.)
