Once The Ug Family stopped performing in Ug Land, the old control cabin for their show was later converted to become this sideshow based on the characters. It is not entirely clear exactly when the Shooting Gallery opened, but it is likely that it opened around the time that Rita arrived in Ug Land.
The Ug Family moved out along with the rest of Ug Land and in 2010 the shooting gallery became the Thirteen themed Demon Shooter, which introduced some new effects alongside some redressed Ug Family effects.
