Cierra and Gianna will return in Episode 491, featuring Jay in a supporting role:
They play the new game Frenzy, another game which makes use of Marvin. (I'm concerned that Marvin's lights don't show up well enough on camera. Future revisions will address that problem.) The players each frantically hit their buttons as fast as they can, causing a bar to move closer to their opponent's side every time they press. First one to get the bar all the way to the other girl's side wins and makes her opponent strip. Naked loser ends up at the mercy of both the winner and Jay, who have a good ol' time with her body.
