Chuckie becomes jealous of Tommy after hearing about his family tree.

Angelica drafts the Rugrats to play her ballet troupe, so she can stage her own ballet recital to prove that she can dance. She did this because (1) she lied to Susie about taking dance lessons (Angelica was expelled from dance school after 2 classes), and (2) she did this to get back at Susie, who was chosen to be a lead at her class' presentation of Swan Lake. Angelica's biggest challenge is to get Chuckie to wear a tutu; he didn't want to, as he feels embarassed wearing one (obviously). The end result -- ""Angelica Lake"", with a pail of water for a lake, and Dil in his high chair as a tree. Meanwhile, Stu, Drew, Randy & Chazz work on Stu's roof, having trouble finding out what caused the roofing tiles to deteriorate.

When Stu goes on a vacation he tells Tommy that he is the man of the house now, and he has to watch over Didi and Dil while he's away.

Chuckie thinks that he's not normal because he can color with either his left or right hand.

Stu & Grandpa prepare a surprise birthday party for Didi. They had everything prepared except for one crucial element -- the birthday cake, which they forgot to get while rushing to get the party together. They take the Rugrats to Bob's Fully Automated Bakery to get the cake. While there, Tommy's gift to Didi, a frog, got away, prompting Dil to try and find it while the Rugrats try to rescue Dil before he becomes a cake. Meanwhile, Betty takes Didi to an English tea shop, where waiters sing songs for every occasion -- to the tune of ""Hail Britannia"".

Grandpa's old army buddy, Roy Davis, is paying a visit, but Grandpa's afraid that he'll be embarrased by his baldness and being out of shape. Meanwhile, afraid that Tommy will stay a baby forever because he's bald, according to Angelica (of course), the Rugrats try to find hair for Tommy.

After seeing Reptar steal some cereal in a Reptar Cereal commercial, Chuckie writes a letter to him complaining about the commercial, with a little help from Angelica. When Chuckie decided to retract the complaint, Angelica said that it was too late, as she already ""mailed"" the letter. Chuckie becomes even more afraid when they go to the Video Cave arcade at ""The Mall"" to meet Reptar who, according to the commercial for ""Reptar's Revenge"" (his latest direct-to-video movie), is ""mad at someone"".

After looking at prom pictures in their parents' high school yearbooks, and the fact that Alisa is going to her own prom, the Rugrats have a prom of their own, complete with a limo and chauffeur (Dil in the Reptar Wagon), so they can decide who can be prom queen -- Angelica or Susie.

In another religious episode, Boris tells the story of Noah's Ark to the Rugrats. Following the story, Angelica sees a weather report on TV, where some rain is forecasted for the area, inspiring Angelica to trick the Rugrats in believing that there will be another worldwide flood soon, prompting her to be the one and only boss and the Rugrats to build an ark and collect two of each animal. However, being the one and only boss will backfire on Angelica, as she is, of course, the one and only.

Intrigued by Chazz's unusual collection of odd asthma inhalers, Chuckie starts a rock collection, with the Rugrats adding on to it. His most-prized possession in that collection is his first rock, which is moon-shaped and reminds him of his father. The Rugrats follow suit and start collecting other items. However, collecting rocks isn't as easy as you may think.

After seeing Miss Carol tie shoes on her video using toy snakes, Angelica becomes an expert a shoe-tying, and proves it by tying everything in the house -- and Chuckie's eternally-untied shoes. However, Chazz thought that Chuckie tied them all by himself. Because of this, Chuckie is afraid that his dad will get angry if he learns the truth, so he tries to keep them tied, at any cost. Meanwhile, the grown-ups try to cook burgers at their cookout.

After seeing someone on TV running for mayor of their town, the Rugrats vote to see who's going to be ""mayor"" of their group -- Tommy or Phil. Meanwhile, Didi and Betty work on mailouts in support of the town's mayoral candidate -- Sheila Swann.

Didi is planting herbs in her garden, including dills, which are used in the canning of pickles. However, after hearing Didi commenting that she's going to plant alot of them, Tommy thinks that the dills for pickles are actually alot of... Dil Pickles, in which all of them would need Tommy's care.

Drew plays a practical joke on Stu, where he unwittingly hurt Grandpa with his newest invention, a robotic bee. This inspires Angelica to play a practical joke of her own on the Rugrats, setting it up so that they would think that Dil pulled these jokes. All this goes on while the Rugrats play a King Arthur adventure.

The grown-ups gather to see old home movies of Stu as a Boy Scout and Grandpa as his leader. This encourages the Rugrats to live the scouting life, but the fun subsides when Dil gets ""lost"".

Rugrats play ball, Chuckie rips his trademark shirt with the planet on it. Chazz gets him another one. But when he finds out that that's not the same shirt as he always had, he becomes a different person named ""Ralph"". Meanwhile, Chazz enters a cooking contest with one of Minka's recipes. Grand Prize: a year's supply of air

Chuckie tries to give a Valentine to his dad.

The babies go on an imaginary tour of America when Angelica and Susie cause some damage at a picnic.

The Rugrats try to stop Fall by stopping the parade, and they do, with a little help of their former friend, Reptar. And in the audience, someone from Euro Reprar Land is watching, in hopes that it would become an important part of the new theme park. Meanwhile, Grandpa recovers nicely, but ends up coming down with a new disease -- the "Love Bug" -- after a nurse named Lulu brought him back to health. In a bizarre twist, this wasn't the first time they met, yet it was the first time they knew each other.

Tommy and the Rugrats give up Reptar for good, and bury all their Reptar stuff in the sandbox.

Stu gets worn out taking care of Tommy and Dil so the adults send him on a spa treatment to make him feel better.

The Cirque du Dummi Bear show is coming to town, and Angelica really wants to go. There's only one problem -- she's coming down with a cold. The good news (to her, of course) is that Charlotte and Drew doesn't know about her cold yet, so she makes a scheme to hide the cold from them and make them believe that one of the other Rugrats have it.

The Rugrats are at a craft & antique fair, where Didi is selling her ""Bird Homes"" -- artistic bird houses that she made. However, she hadn't made any money, or as so much as a glance from someone walking by, due to her competition. Meanwhile, Grandpa sits down on an antique rocker to tell a story to the Rugrats; naturally, he falls asleep. The rocker is up for auction, but with Grandpa still in the rocker, the Rugrats though that it was Grandpa who's up for auction, so they find a way to buy him back.

Angelica graduates from the ""Mind My Manners Charm School"", where she is taught good manners. She puts her knowledge of manners to work when an important guest, an executive for Charlotte's company, is invited to Drew & Charlotte's for dinner, leading to Angelica teaching the Rugrats some manners.
