Superintendent Blomptkins makes the students not wearing clogs submit to woodworking class, where they are forced to make their own clogs. Lee and Cam go to Barrage's house, where the Hazmats take the house away on a truck to a hidden archive. There they find Barrage's old computer but it is broken during a chase, the hard-drive is salvaged. Meanwhile, Biffy and a curious Kimmie sneak into his parent's workplace, but other Hazmats have already removed most everything and are about to demolish it. There they find out that Kimmie's mother owns the company his parents work in, Biffy recognizes her mother as the person who congratulated Lee at the dance. They both escape before the demolition. Back at school, Tina refuses to make clogs and Holger, after a failed attempt to join the cheerleaders, burns his own pair when he dances. They are put in a clog-like cage, "The Mega-Clog", and Lee and Cam find themselves guided by the Tatzelwurm to beneath the woodworking class. They help the students escape to the library but Lee is caught. Mrs Ping catches Blompkins attempting to punish Lee with a clog-launcher, which results in a "clog-gun" fight where Mrs Ping ultimately wins. Blompkins is fired, and Tina and Holger are released by Lee. At home, Lee finds an image of a submarine in the hard-drive. Meanwhile, Kimmie's mother decides to power up Barrage and bring him back as principal.
