Lampo appears before Tsuna and the sleeping Lambo and announces that Lambo's trial will take place at an amusement park. To pass Lampo's trial, Lambo has to gather three stamps by riding three amusement park rides and enter the castle which Lampo resides. The rides are the teacups, a miniature race track, and a course through a robot museum. While going through the rides, Verde hacks into the amusement park systems in order to perform various tests on Lambo and to deduce why Lambo has such a high resistance to electricity. After Verde captures Lambo with a robot, Lambo's fear causes him to release all the electricity Verde shocked him with and which causes an explosion destroying Verde's robot and sends Tsuna and Lambo into castle. Lampo initially deems Lambo has failed the trial since Tsuna missed stamping the paper but decides to pass Lambo after seeing the electricity Lambo released.
