Players are first given a sheet identifying seven breeds of Stromlings: Stromling, Stromling Pirate, Dark Admiral, Dark Spiderling, Maelstrom Ape, Maelstrom Mech, and Spider Boss. Then, players see a LEGO city modeled after Zorillo Plaza which constantly scrolls to the right. Minifigures and Stromlings alike appear in the windows of various buildings. Players must shoot down as many Stromlings as possible, but shooting an innocent minifig results in an instant loss. The more Stromlings are shot, the more minifigs are sent into the LEGO Universe upon the mission's completion.
