Party Pooper is very protective of humans, to the point that they are willing to sacrifice their lives to protect humans. They have a quiet demeanor which is the opposite of a Partygoer. They are quite capable at combat and have knowledge of the different levels of the backrooms. They are very nice and friendly. Don't attack a Party Pooper or else they will give you to a Partygoer. All party poopers look similar and no one knows what they look like underneath their mask.
