Two Cleaners in full hazmat suits opened the truck compartment, one holding a flashlight to inspect, while the other stood guard with a specially designed gun filled with syringes.

"Hurry up, the smell is making me nauseous after the beef tripe I had this morning." The vigilant Cleaner yawned, lowering his weapon.
"You've got a good appetite. I've been a vegetarian for years." As the flashlight was turned off, the Cleaner just turned around when suddenly the pile of corpses behind him burst open, and a figure emerged!
