Todd gets transferred to Wayside School, a school that was accidentally stacked 30 stories high instead of 30 rooms sideways. He is assigned tries to Mrs. Jewls' class on the 30th floor, where he attempts to fit in with the class, usually with mixed results. However, due to his failure to cope with the school's unorthodox system of learning, Mrs. Jewls writes his name on the chalkboard and puts a check mark next to it.

The teacher threatens that he will be sent home on the kindergarten bus. The class is about to be crushed by the trash compactor that was accidentally on the 30th floor and the machine would work every time the PA comes on, Todd's outbursts start, and Mrs. Jewls writes his name under the word "discipline" and sends him home on the kindergarten bus.

Mrs. Jewls and her class play dodgeball, and Principal Kidswatter tags Todd and is finally tagged. Mrs. Jewls pronounces Dana as class president. While Todd is sent home again on the kindergarten bus after he does more outbursts to Mrs. Jewls, the trash compactor is on again.

Meanwhile, Mr. Kidswatter tries to ease his stress with a new machine, called "The Wizomatic 3000", he bought for $19.99. At the end, Myron and Dana reconcile and become best friends again, and Todd tries Myron's brain-listening glass trick on Shari (only to find out it truly does work as he hears horses, pinball, and karate).

"Myron vs. Normy": In order to avoid getting in trouble, Myron pretends to be Normy, his made up twin brother. When he returns to the class, everyone thinks he is cool (and in Dana's case, sweet and cute) and they want him to be class president.

Feeling bad for Maurecia, Miss Mush puts her dead rat in an old knight suit so Maurecia has someone to dance with making Todd jealous.

When Dana bumps Jenny's bike onto the ramp, it comes back, only with the seat signed by Mrs. Zarves.

"Kidswatter: The Movie": The kids are assigned to make a movie about Principal Kidswatter for the new movie making class, and Todd is cast in the lead role. However, he soon becomes even worse (if not just as bad) than the real Kidswatter.

She hates it because she is last, slow and late for everything. Kidswatter tries again and makes everything squared become round again. Meanwhile, Todd, Dana, and Myron join Maurecia.

"Upside Down John": It's the 30th floor science fair today and John is showing his science volcano. However, he hates how it turned out. John then starts to think this is so because he does everything upside down.

In the end, Mrs. Jewls tells John, without the help from Todd, Maurecia, Dana, and Myron, that being upside down is not a bad thing. Meanwhile, Kidswatter is doing an I.Q. test to see if he is smart.
