Crawler ration boxes, promised an "extra toasty" upgrade as half of the doomsday quest's reward.
Alongside a year off the Indentureship contract, the reward listed for This Is How the Gristle Grinds is that all food boxes will be upgraded with an "extra toasty" option.
The joke lands exactly as the system intends: the crawlers are being offered a menu upgrade in the same message that tells them a god is about to turn the ninth floor into a cremation chamber and that everything and everybody on the floor is going to die.
Standard crawler ration boxes, now with an added preparation option.
The system's punchline reward for surviving a floor-wide cremation.
