Pillow- BFDI

Pillow is apathetic and eccentric. Similar to Golf Ball, Pillow is interested in research. Her research is seemingly random and made up, such as when she misinterprets Teardrop's arm fluttering as "not caring", suggesting that it's due to "care spirits" leaving her body. She seems to enjoy taking notes, as she can be seen writing in a sketchbook when Donut infected himself with the Twinkle of Contagion, although Pillow's Official Character Guide biography mentions that she doesn't know how to write, hinting that she might draw pictures instead.[note 1] It's also hinted that Pillow is illiterate, as she picks up Book to look at the pictures instead of reading her.
