Wannabe St. Valentines Day Massacre ghosts are a pair of gangster ghosts that want to make their own mark on history.
Just before Valentine's Day, two gangster ghosts attacked a high school. They were intent on making their own mark on historical mobsters, by causing their own St. Valentine's Day Massacre. The Ghostbusters confronted them in a gymnasium while it was being prepared for a Valentine's Day Dance. After destroying much of the surroundings, the Ghostbusters trapped the ghosts in one Trap.
- The ghosts mention Al Capone, who appeared on The Real Ghostbusters episode "The Ghostbusters Live! from Al Capone's Tomb!" and New York's Five Families, the five major Italian-American Mafia crime families.
- Their being caught in one trap also mirrors the time the Ghostbusters captured the Scoleri Brothers.
