Chocolate Mallow, or Choccy Mallow for a slightly shorter version, was designed to be a babysitter. He was never planned to be sold considering the company didn't want to have to deal with tons of lawsuits, instead he was just intended to entertain and babysit kids when they got lost in the factory. Choccy Mallow loves kids, specifically toddlers. No don't screenshot that and cancel her on Twitter, it's all platonic and familial. Choccy loves kids so much in fact though, that she can become incredibly protective of them.

One day when he saw a child getting yelled at by their mother after the child had gotten lost she wanted to act out, but didn't in fear of making the situation worse for the child. When he saw the child being hit on the arm though, all hell broke loose and she tore the mother to shreds. He was shot on sight, but managed to stagger away and fix herself up. Now she wanders through the halls. If you're a child she'll protect you, if you're an adult he'll attack, though not necessarily kill you.
