It's time for the annual Flying Rhino Junior High Games, in which students compete against one another in the glorious field of athletic competition. Everyone has been practising their skipping, pogoing and yo-yoing... well, almost everyone. Billy, a natural athlete, feels that he doesn't need to practise. Earl, irritated by Billy's arrogant posturing, strikes a blow for uncoordinated geeks everywhere by transforming the school into the site of the original Olympic Games: Olympus! Now Billy, Marcus, Lydia and Ruby must beat the ultimate competitors -- those overbearing Greek gods -- if they have any hope of saving their school. Fortunately for our heroes, guess who didn't come prepared?

Inspired by a class lesson on pirates, Johnny and Rod start shaking down the other students for their milk money, terrorizing the school. But when Earl hears Lydia pass judgement on the two thugs -- ""Those guys are low-down, dirty sneaks. They're no better than Earl."" -- he loses it. After all, his stellar villainy is leaps and bounds above their amateurish thuggery. To prove his point, he dons a pirate's hat and becomes the infamous Peach Fuzz Beard, morphing a pirate ship into existence and commanding it from the boiler room. His scurrilous crew drafts our gang (Billy, Ruby, Lydia, Marcus, Johnny and Rod) into service. The pirate ship embarks on a pillaging voyage through the school in search of ill-gotten booty with our unhappy heroes in tow. Well, actually, not all of them are unhappy. It turns out Ruby has decided that the pirate life is for her, delighting in her position as ship's treasure-counter.

Our gang must convince Ruby that stealing is wrong if they have any hopes of tu

It's Career Day, and a variety of career exhibits have set up shop throughout the school. Marcus feels sorry for Buford. No one seems interested in his janitorial exhibit. Marcus guilts the gang into visiting by reminding them how helpful Buford has been in their past adventures. Pleased by their visit, Buford enthusiastically tells the kids about his general duties. He gets into plumbing, explaining such things as clogs, traps, sewer gas, etc. But the kids show no interest. Buford picks up on this and slinks off, his feelings hurt. Marcus is angry with his friends. Made to feel guilty, Ruby argues with him. She really likes Buford, but she doesn't think that he should be pushing sanitation engineering as a career. Making a living in a sewer? ""Come on, what kind of a crazy person would want to work underground for a living?""

Earl is outraged! He works underground for a living, and he's certainly not crazy! He transforms the school into a sewer, complete with noxious sewer gas, bursts

Visiting the school for a routine safety inspection, a fire chief drops by the class to deliver a lesson on emergency preparedness and fire safety. An ensuing safety tour of the school is complicated by Earl, who figures that if Flying Rhino Junior High fails the safety inspection, the school will be shut down, and he will have the building all to himself! A few keystrokes later, the enviromaster has morphed the school into the most dangerous place imaginable. Suddenly, everything is in a state of disrepair, exposed wiring abounds, the cafeteria floor is covered with grease, and improperly labeled household cleaners lie about. Unfortunately, the visiting fire chief turns out to be a magnet for disaster, and our heroes have their hands full trying to keep him out of trouble and in one piece
