Fun Gun is Harley Quinn's modified grenade launcher with the ability to shoot confetti, glitter, powder bombs, and bean bags.
History[]
Quinn used the Fun Gun when attacking a Gotham City police station in order to break out Cassandra Cain. In addition to using it as a normal gun, she used it as a blunt force object while fending off officers of the GCPD and men released from holding cells after breaking out Cain, leaving it behind while going after Cain and making a speedy exit from the station.[1]
