In order to get two Cynthia toys Angelica pretends that she has a twin to get double of what she wants. Everything goes well until the babies like her twin better then her so she decides to go back to being herself.

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

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.

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

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.

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.

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.

At home, the Rugrats watch an old, ""Bonnie & Clyde""-type film on TV with Grandpa. At the park, Angelica and Dil used what they saw to play ""Bonnie & Clyde"", with Angelica stealing food from other kids and Dil playing accomplice. Meanwhile, at the park, Grandpa continues to watch the movie on a portable TV set, getting the other adults to do the same.

Tommy and Chuckie are getting sick and tired of each other, so they decide to hang out with people who act like them. Later on that gets annoying and they start to miss each other.

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

This episode picks up where Rugrats In Paris has left off -- with the entire gang now back in the good old US of A, with Chazz a newly-married man, and, most importantly, Chuckie gaining a new mother and sister that he likes. But if you think that the Watanabe-Finsters are going to be in a total state of bliss from now on, think again -- as long as there's Angelica, there cannot be total bliss. And who else but Angelica would put a damper on Chuckie's happiness? While Kira studies for a fairy tale play (which involves Cinderella), Angelica tries to trick Chuckie into thinking that he'll be living the same life as Cinderella -- virtually being a slave to Angelica and Kimi, while everyone else gets ready for a party that will celebrate the newlywed couple's adoption of each other's child, a couple of weeks after their marriage.

At the Finsters, Stu builds a treehouse for Chuckie, Kimi, and the other Rugrats to play in. After Kimi took Cynthia from Angelica (without asking, of course) to play in her treehouse, the Rugrats imagine Angelica as if she was a monster from the jungle, a la ""King Kong"".

After Grandpa told the Rugrats one of his war stories, the Rugrats rescue Dil's bottle as if they're at war.

When Kira & Chazz felt that Kimi is homesick for France, they throw her a party and shower her with gifts, all with a French theme. However, by doing so, they ended up not giving Chuckie any attention.

When Angelica decides to play "business luncheon", the Rugrats wanted to play too. However, Angelica told the Rugrats that they can't play unless they're able to wear grown-up clothes, tell jokes and not wear diapers -- her idea of growing up. Susie tries to make the Rugrats grow up, so they can join Angelica.

Tommy talks to Dil about the things in the backyard, like grass, the lawn mower, Spike's doghouse, even Spike's "poopie".

Angelica recently received a Cynthia talk show outfit, while Kimi got one of those toys that you push beads along pipes. While the other Rugrats were getting ready to play "talk show", Chuckie wanted to play with the other toy, but broke it after tripping on it. Afraid that he'll make Kimi sad, he hid the broken pieces away. Angelica, however, saw the broken pieces, and organized a talk show on the Rugrats' most intimate secrets, just to find out who broke it, as well as entertain herself with a recording of an angry, upset Kimi on tape.

The grown-ups prepare for a block party. After Betty warned the Rugrats that Dil will become a watermelon if he eats too much of it, they thought that it happened when Didi took Dil inside to clean him up and was replaced at that spot with a watermelon, while they saw Chazz making balloon animals. The worst part is that watermelon is going to be part of a watermelon-eating contest.

Kevin McNulty, one of Grandpa's old friends (and of course, related to Timmy and the McNulty boys), goes through the secret initiation in order to get into the Loyal Order of Wombats. After seeing this, the Rugrats have Dil go through something similar, so he could become one of the ""Big Babies"". In turn, their fathers mimic the Rugrats, on a bet that they could do everything the Rugrats do.

At the park, Angelica wants to play with a couple of 4-year-old girls. However, those girls dislike anyone who's 3 years old, like Angelica. So, she convinces the girls that she's 4 years old by trading Phil in exchange for their jelly-based toy. In return, Angelica promised that she'll be nice to the Rugrats. However, Phil wants much more than that. Meanwhile, Grandpa tries to teach Spiffy, one of Spike & Fifi's new puppies, n

The tykes misconstrue something their babysitter says about not liking dill pickles.

The Rugrats coat Dil with ""Baby Power"" (baby powder), so he could be strong enough to beat Spiffy in a game of Tug-Of-War. Shortly afterward, though, an earthquake strikes the city, leading the Rugrats to believe that Dil has too much ""Baby Power"", so they try to find a way to make him normal again.

The earthquake has given Stu an opportunity to try special earthquake safety helmets on the Rugrats, the newest product from Pickles Industries, ""the first name in disaster"".

When Hollywood celebrity Mack Granite visits the coffee shop, he got more than a decent cup of coffee -- he also finds the perfect person to play the role of a little girl in his next film. And Kimi is -- that girl. But, when Mack says that Kimi is going to be a star, the Rugrats though that she'll be up in the sky, twinkling.

The families go on a resort vacation, but are unable to relax when they're forced to share one room. Meanwhile, the babies look for treasure.

Angelica orders a timid playmate to act as her errand boy.

Angelica convinces the babies that the parents are looking for the fountain of youth.
