CatNap.

CatNap is the main character you'll encounter in the third chapter of Poppy Playtime, and one of the ones that players have come to rely on the most. Also known as Experiment 1188, CatNap was part of the Big Bodies Initiative and really showed it off with huge elongated limbs and a slouchy figure that towers over you. CatNap has a version of Gaza Poppy installed in his respiratory system, which, while non-lethal, causes horrific hallucinations.

He was originally created to serve as a caretaker at Playcare, caring deeply for all the other critters and making sure they get proper rest. However, his goals begin to blur when he uses his gas on the critters, causing them to undergo a dark change, subsequent insanity, and begins to devote himself to the Prototype.
