Ned's father gives Ned a vintage "Captain Ocelot" action figure after his son takes an interest in the show. Ned's mother, however, throws it out, and Ned and Newton have to go to the Friendly Falls Dump to find it again. Afterward, they find out that the dump owner is actually the retired actor who played Captain Ocelot.

The company that manufactures Zippo Newt Food has changed the formula, which leaves Newton unable to control his morphing ability. Ned and Newton go to the corporate headquarters to complain, but the president of the company refuses to go back to the old formula until Newton demonstrates that the "new formula" causes newts to grow six feet tall and change into different forms.

Ned's parents have the flu, and want Ned to do the day's chores. Newton tries to help, to get them done faster, but he ends up being incredibly destructive.

The Friendly Falls Future Fair has been reopened after it was closed in 1964, which makes Ned excited. The lineup to get into the fair is huge, though, so Newton sneaks him in so they can see the exhibits. Ned is dismayed to see that they haven't been updated since 1964, and most of the displays are ridiculous: there's a car with a record player mounted on the dashboard for a "car stereo system", a kitchen where malfunctioning robots cook food, and even robotic pets (much to Newton's shock). He goes back to his parents just as they get to the front of the line, and says he doesn't want to visit the Fair anymore.

Ned's teacher has developed a new alphabetical desk arrangement, which unfortunately puts Ned in the back of the class, and Linda Bliss at the front. Because he wants to be able to sit right behind her, Ned and Newton arrange various schemes to make sure the few kids in between Ned and Linda get taken out of class, either by moving, being transferred, or having their last names changed. But at the end, when it looks like Ned and Linda get to sit with each other, Ned's teacher grabs him away from Linda and introduces to him two pairs of identical twins named Jenny, Kenny, Penny, and Lenny, who are told to sit between Ned and Linda, much to his disappointment.

After a freak accident, Ned and Newton switch bodies. They have to try to act like each other until they can switch back, but this is harder than it sounds.

Ned has invited two girls, Linda Bliss, and a new girl, to the grand opening of the Friendly Falls Aquarium. Newton notices that Ned is anxious about this, and comes to the conclusion that it's because he's lonely. To help him out, he invites 310 more girls, to keep Ned company.
