Triple Trunks met Rick and Jerry at the bar at the Immortality Field Resort. He was drinking four glasses of purple liquid simultaneously and overheard the story Jerry told Rick, which he enjoyed. He started talking with Rick while Jerry was in the bathroom, and mentioned that he knows a place where the ladies drop their panties for anyone bi-pedal. Jerry was not interested, however, as he was still in love with Beth.
