Eddie Swarm

An Eddie Swarm is created by casting more than one person to play Eddie and Columbia to perform "Hot Patootie" in The Rocky Horror Picture Show. This casting is usually done at Rocky Horror conventions for the casting of the "All-Star" shadow-cast to extend the opportunity to perform to more than a single person who plays Eddie, as this character only has one scene. Eddie Swarms are occasionally also performed at non-convention screenings of the movie, but are not common.
