Lynn Stacy  was going to be Peter's date on Halloween but things didn't go as planned.
On one Halloween, Peter planned to attend Donald Trump's party with Lynn Stacy. However, she mistook Slimer, who was wearing a costume resembling Peter, for her date. Slimer kissed and slimed her. Utterly disgusted, Lynn stormed off and refused to explain what happened to the real Peter. Naturally, Peter was angry when he realized Slimer was involved.
