They're cupcakes, but you happily oblige and chow down on one of the many baked goods that now litter the floor.
You immediately regret the decision. They taste KIND OF TERRIBLE! You can tell that the cupcakes themselves are well-made and carefully baked to perfection, but there's a faint taste of ROTTING MEAT underlying the whole flavor profile. You suspect spending time as an UNHOLY DEMONIC BEAST tainted them a bit, which is a shame.
You figure it's probably a good idea to avoid eating the DEAD MICE too, for that and many other reasons.
