Pillow [SMUT]

Pillow is apathetic, carefree, 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. In "Balancing P.A.C.T.", she is shown to be apathetic to this, nonchalantly saying, "In my studies, half my studies have been proven ineffective. I just can't take those odds." 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. Pillow is also illiterate. having never been taught by her parents. She can be impulsive and care little for others, such as licking Lollipop out of hunger. She is shown to be apathetic as she was very casual about dipping Price Tag into acid in "The Worst Day of Black Hole's Life". She didn't seem to be capable of knowing why Price Tag would have a problem with this and nonchalantly says "That's fine" when Price Tag says they'll die. In "Fishes and Dishes", she has little to no problem throwing the safe team members off of the hotel. She can be condescending, which is shown when she calls Barf Bag's suggestion "ludicrous". The condescending aspect of her character is seen again in "You Know Those Buttons Don't Do Anything, Right?" when she is shown mimicking Book as she tries to reassure their teammates. It is also seen in "Getting Puffball To Think About Roller coasters", when Nickel says to grab the garbage and then Robot Flower, which Pillow responds with "Why did you say to grab the same thing twice?".

She seems to have a morbid interest in death and destruction. In BFB 1, she only joined Death P.A.C.T. because she heard the word "killing". In "You Know Those Buttons Don't Do Anything, Right?", it's revealed that she's had a history of killing that the Death P.A.C.T. members were hoping she would stop. In "Getting Puffball To Think About Roller coasters", she casually admits that she wants Two to ride Are You Okay's roller coaster so that they'll die. In "The Seven Wonders of Goiky", it is revealed if Pillow won the Limitless Power, she would use it to "study how many people would be blown up with just one zap", involving her zapping the other contestants for her own amusement. The same episode suggests that she acts like this as she believes she's more likely to succeed by killing compared to trying to help others. In the same episode, she wants to damage her team's roller coaster more, instead of repairing it. In "Balancing P.A.C.T.", she is interested in Robot Flower's violent tendencies, asking her "do your violent tendencies come from something deep within, or is it just for fun?" In “Outbreak At Stake", when Two’s message on the challenge via video projection (survive as long as possible) is distorted due to bad signal, Pillow assumes the challenge is to massacre and wipe out her team, causing her to go on a murderous rampage though Gelatin’s Steakhouse that eventually culminates in her being blown up by Bomby willingly igniting himself to put an end to her terror.

She believed that killing equals good luck, hence why she tries it on every occasion, but after she caused her team to lose in "Outbreak At Stake", and hearing Teardrop had been eliminated because she died, she is shown to be regretful after learning that her research was wrong. Pillow is also seen to be disgusted at the mere mention of doing or having someone doing a good deed to her, as she pukes some of her fluff in "Oneirophobe's Nightmare". She then decided to resort to try other methods of good luck to win, such as doing a good deed and showing kindness.
