Once inside the Bong World he races to Eebee and activates a bombe he has secretly stapped to his chest. It explodes killing Eebee as well as him but returns the bong's victims to their bodies. Jimbo's soul, still being trapped within the bong, Takes Eebee's place as the ruler of bong world. Immediately after learning this he uses his newfound control over the dimension to generate a set of hotweels and plays with them beside his stripper avatars.
