Blankfication is a term that refers to any amount of damage brought about by The Nap's fabric. The word comes from 'blanket'.
To people and animals
Many of the world's inhabitants (roughly 85%) have been turned into fabric. Their deaths are incredibly painful, as they, from the bottom up watch their limbs and organs turn to fabric and stop functioning. Eventually their entire body is converted to fabric and the fabric can either fall to the floor in bundles or it is 'sewn' into the surrounding. A person who was blankified and sewn into their setting appears as a vague outline of a person, the pained expression of their face, almost like a permanent stain.
Animals are also subject to this same fate, though due to their nature have been combined into horrifying mutants before being blankified. These amalgamations are also sewn into the surroundings.
To objects and locations
Buildings and objects can be blankified too. It is much more rare, but it does happen. Some buildings have vital support structures blankified, causing them to collapse, causing fires and much destruction in the world.
In rare instances to objects shaped like people (such as statues), their forms are twisted and made terrifying. This can be seen in 'mannequin', when Mint sees the weird statue in front of the hospital.
Half-blanks
Half-blanks are people who were not fully effected by blankification.
They shamble around as grotesque husks of humans, some of them retaining more of their brains than others. Usually these victims are pretty rare, and they are usually captured by Foamfield Research before anyone else can find them.
It's only been observed in humans.
Mint comes across one or two of these half-blanks, at a loss as to what they are. She chalks it up to the weirdness of Foamfield. To her they appear as strange rotted flesh and fabric piles, almost just appearing like old garbage, decomposing and withering away, the world reclaiming them.
