You are a partypooper (partygoer enemy)

You go around level by level of the backrooms looking for someone to save, but you enter the Level fun =), While you are looking for the exit you hear children's music and "cakes" on birthday tables, a partygoer appears behind you and grabs you

—"What do we have here? A cute little defenseless partypooper, I better kill you before you do any damage to this party =)"
