After returning from busting villain Arson Boy, Henry and Ray sneak away from a messy Man Cave from Schwoz's visiting family as Ray introduces to Henry his secret paradise, the "Mannex". However, Charlotte, Jasper and Schowz discover the room and get jealous after Ray and Henry kick them out, the former restricting the room as "crime-fighters only". Meanwhile, Piper, after getting arrested for running over a cop, bargains the two cops into cooking a soup for them to bail herself out of jail. After Henry delivers a karaoke machine to the Mannex, he and Ray discover the others in their own secret room in an effort to one-up them. After Schwoz destroys a life-size "fiesta-size" churro, Ray turns to his immature tendencies and threatens to blow up the Man Cave in vengeance. The four's bickering causes them to accidentally press the Man Cave's self-destruct button, causing them and Schwoz's family to evacuate as the Man Cave's explosion causes a town-wide earthquake (which occurs at the same time Piper gives the completed soup to the cops without spilling a single drop.) Mourning the loss of their hideout, Ray and Schwoz reveal they built nine additional Man Caves (five destroyed so far) to compensate for Ray's irresponsible demeanor. However, upon checking out the new Man Cave, a Mole Person appears and presses the self-destruct button, once again causing an earthquake.
