After Mr. Garrison's election victory, many people visit SpaceX to go to Mars in fear of TrollTrace.com releasing their internet histories to the public. Cher, along with Heidi, Cartman, and Butters, are among the group and join in on Elon Musk's tour of SpaceX.
Cher appears to be somewhat absentminded, as she preforms her songs, with none around paying attention to her.
Cher wears a black dress with white patterns and white fur edges. She is hunched forward and has blonde dyed hair.
