Last Stall on the Left
Principal Slimovitz talks to Hannibal McFist, Bash's mother, and Bash Johnson about Bash's behavior. He gives the details of all of the times Bash bullied someone. Bash's mother claims that she won't believe that he could ever do such mean things. Bash states that he was being framed. They then hear some kids saying that they saw the ninja. Principal Slimovitz then runs after them to see the ninja. His car seems to get constantly destroyed.
Slimovitz is a nervous yet overly optimistic principal. Although he's stuck in a school that's alway dealing with monsters and robots, Slimovitz is always tries to deal with it and hopes that the school will be free of constant damage eventually. He is easily terrified whenever he gets attacked, failing to follow his own rules for the drill because the real robot scares him. However, he is at least fair, often giving kids detention if they break rules. He does find some crimes more annoying than others, though, saying the one thing that he despises more than tour abandoners are tattletales in "Randy Cunningham: 13th Century Ninja".
