After Frank defeats the psychopathic clown Adam MacIntyre, he stops the Space Rider using the control panel. Greg, who has been held hostage by Adam, then steps off the ride in a dizzy state. Frank offers to take him to some other survivors in the Security Room, and Greg reveals that he knows a shortcut there.
He then leads Frank to the women's bathroom in Wonderland Plaza, and tells him that a vent in the ceiling will bring him to Paradise Plaza. Once Frank and Greg are in the bathroom, jump up onto the sink and go over to the left-hand side to find the shortcut entrance, which will take you to the women's bathrooms in Paradise Plaza. After Frank and Greg travel through the vent, he follows Frank to the Security Room and cheers when seeing Otis safe and sound.
