Earl is furious when Mrs. Snodgrass's class doesn't recognize him as one of history's greatest villains. To show everyone who the world's greatest fiend really is, he launches a full scale, tactical war, and he sends a troop of treacherous, life-sized comic book villains in to conquer the school. Although the boys think that they are the only ones with enough comic book knowledge to thwart the evil villains, they soon realize that they know nothing about these characters! Fortunately, Lydia's knowledge of comic book trivia is tremendous, and she's the only one who can identify each villain's weakness. Lydia and the gang defuse Earl's latest attack, once again saving Flying Rhino Junior High from impending doom. Impressed by Lydia's trove of comic book knowledge, the all-male comic book club realizes that boys and girls can not be stereotyped, and it invites the girls to join.

Billy is the only student who didn't make his own Earth Science project to be judged in class. He put off building the ""weather nullifier"" that he designed, using the time to play baseball and watch TV instead. With no time left to make the project, Billy ends up having to buy one. Before the judging takes place, Earl submits his own project, a ""preter atmospheric generator"" that he believes will win. When it doesn't, Earl angrily turns it on, unleashing a tornado, a mudslide and a thunderstorm on the school! When Billy's nullifier fails to work, he finally builds the one that he was supposed to for class. Only then is Earl's weather attack stopped, and a lesson in the perils of procrastination learned.

Curiosity gets the best of Billy, Marcus, and Ruby when they try to sneak a peek in Lydia's class journal. Lydia, understandably upset, accuses them of snooping, and informs them that her journal is private. Besides, who's to say that she's been writing about them? She could be writing about anyone: her parents, her uncle's cat, Earl. Earl? Convinced that Lydia is writing about him, Earl transforms the school into a 1960's spyscape, and he dispatches a rogues' gallery of spies to retrieve the document. With time ticking down, Billy, Marcus, Ruby and Lydia must outmaneuver the colorful henchmen and deliver the journal into the proper hands (in this case, Mrs. Snodgrass, patiently waiting for them to turn in their journal assignments). In the end, Billy, Marcus and Ruby forego the opportunity to ""sneak a peek"" at Lydia's journal, learning a valuable lesson about the need to respect the privacy of others

It's student election time, and Billy and Ruby are both vying for the coveted title of school president. Though initially friendly, their rivalry heats up, and before you know it, the mud starts flying. When Earl's petition to include his name on the ballot is rejected, matters are complicated by the late entry of a mysterious third candidate. Buoyed by a glitzy ad campaign (compliments of his spin doctor/campaign manager, the Phantom), the third candidate (none other than Raticus in a clever disguise) shoots ahead in the polls. If Billy and Lydia are to defeat this upstart, they must clean up their acts and work together.

In the end, they learn that ""no one's a winner when you don't play fair"" -- a fact confirmed by the other students who, disgusted with the dirty campaign, end up electing Fred Smertz as a write-in candidate.

Ask anyone what Billy's favorite movie is, and they'll tell you: ""Daredevil Donnelly and the Amazon Adventure."" He's seen it 20 times. And with all of the hype surrounding the cheeseball classic release to video, Billy has caught Daredevil Donnelly fever all over again, suddenly patterning himself after the film's dashing hero. He shows up at school sporting Daredevil Donnelly's trademark fedora, toting Daredevil's trademark lasso, spouting his trademark lines (""Make way for adventure!"", ""Stand back and be amazed!"", etc.). He's even got Daredevil Donnelly's bluster and bombast down pat. Well, Billy's heroic posturing proves too much for Earl, who decides to transform the school in a real-life Amazon adventure. But, alas, the thick-headed Raticus inadvertently triggers the morph while Earl is topside fixing a camera and, before you know it, the Phantom (in a less-than-clever Heidi disguise) has joined our heroes on a hair-raising ride down the Amazon.

Over the course of the adventure,

When Ruby's poor eating habits result in an in-class fainting spell, Nurse Cutlip takes it upon herself to lecture the kids on the importance of proper nutrition, exercise and rest for the promotion of health. But down in the boiler room, Earl scoffs at the notion. Eat healthy? Exercise? Ha! He eats terribly, he doesn't exercise, and he's in fine physical form. But when Nurse Cutlip holds up an old photo of Earl as a warning of what could happen if they don't take care of their bodies, Earl becomes enraged. He morphs the school into his body, determined to give the kids an up-close and personal look at just how healthy he is. Our heroes are ambushed by a gang of bacteria, unpleasant thugs who have laid claim to this turf (Earl's body), and who challenge our heroes to a rumble. Marcus realizes that they are no match for the bacteria, but they know who is: the body's defenders, the white blood cells. Unfortunately, the white blood cells are a weak, sickly lot, lacking in self-confidenc

When Marcus inadvertently breaks the sink in the boys' bathroom, he bolts, allowing Johnny to take the blame. But when he hears that Johnny may face suspension, Marcus instantly regrets his decision not to step forward. Of course, regretting his inaction is one thing. Actually having the courage to step forward and admit to his mistake is something else. While Marcus wrestles with a guilty conscience, Earl, a regular fall guy during his high school days, decides to teach Marcus a lesson. Inspired by an in-class discussion of Lewis Carroll's ""Through the Looking Glass"", Earl sends our heroes to a bizarre alternate mirror world. There, they encounter weird mirror versions of our Rhino regulars: a sharp and eagle-eyed Principal Mulligan, an erudite Rod Harwood, a squeaky-clean Fred Smertz. As it turns out, our heroes have quite a reputation in this mirror world -- and not a good one. It turns out that their mirror-versions are some Class A troublemakers -- and our heroes are paying the
