Party-poopers seem to be a human-like entity wearing a blue mask with a frown, overview: party-poopers no longer exist in the backrooms after the fun war. These are safe creatures in the backrooms that are normally keen to help wanderers who have no-clipped. the fun war: this happened on September 6th 2020, the party-poopers got mad at the party-goers then as they were about to win, the party-goers made the turn table and won. Edit: they are back! Thanks to Broogli for kinda bringing them back!
