A video played on the screen showing Maxum Man and Golly Gee Kid's old teacher, Sensei Jimmy, Master of Side-Fu. Everyone at the academy was accepting to be get beat up, all except Eric. Sensei Jimmy enlisted Eric as the title of janitor for his 'special' training. While Eric was in his 'special' training, Sensei Jimmy signed everyone up for the Side-Fu Tournament against Master XOX's henchmen from the Henchmen Academy. Both Kitty and Vana lost their matches to the henchmen, and Trevor had forfeited himself from the match. Eric had to replace Trevor and put his training to the test. Eric won the crowd's love with his technique but he loses to his opponent by the latter hitting him with a 'trash tornado'. Sensei Jimmy was proud of how Eric made use of his training and made Eric clean up the gym for he was a the janitor, after all. The moral of the story is to never give up.
