The Womp Rats Club was a group infamous for their swoop bike riding around the Grand Arena battlefield, specifically the Mos Espa Waystation, which was a location used by the Hunters of the Outer Rim on the planet Vespaara. By the year 9 ABY, they had taken over Swooper's Rest, marking it with a roughly made sign that read "Womp Rats Club" in Aurebesh. This sign also featured a womp rat skull illustration on the left and an arrow pointing down on the right, along with a poster showing the outlines of five matching swoops, with one being larger, haphazardly attached above. Evidence suggests the group had at least four members, as they parked their matching swoop models in different colors in front of Swooper's Rest.
The competitive video game Star Wars: Hunters was the first place the Womp Rats Club was referenced. Their addition to the game happened when the Mos Espa Waystation map was introduced in version 0.16.0, which became available on March 7, 2023.
