Good question Anon, since a lot of people might not know. They are the Walter Girls!

The one on the left is Walter Girl Carolina, and the one on the right is Walter Girl Paige. They are played by Carolina and Paige, who are Sam’s roommate and Bunny’s girlfriend, respectively (though it’s hinted that David’s girlfriend, Gabi, could become Walter Girl Gabi pretty soon). Off the stage, they are responsible for selling merchandise at cons and are also the ones who process and ship out the merchandise orders for the band’s online store.
On-stage, they are meant to be employees of Walter Robotics and are responsible for tune-ups and general maintenance of the robots onstage. Their identities, race, and biographies are kept as classified information in the SPG lore.
