Middle School: Wild Overboard

Dil's First Steps and Angelica's Dream Yacht

While playing with a Follow-Me-Reptar toy, Tommy feels bad that his brother, Dil can't play with the Rugrats since he can't walk. He and friends try to get Dil to walk, but he has quite a bit of trouble with it. During one of their attempts to get Dil to walk, Stu's talking on the kitchen phone to Didi and he looks out the kitchen window and sees Dil seemingly walking (he was actually being held up by Phil and Lil).

When Betty, Charlotte and Chas are told what Stu saw, they don't think Dil was actually walking and tell Stu that Dil's still way too young to actually start walking (with Betty pointing out that he won't start walking for at least a year). The adults start reminiscing about when their own children first started walking, while the babies and Dil (and later Angelica) do the same thing:

Angelica tells the babies that she started walking after she first saw another baby with his mom holding a cookie in his hand. She got out of her stroller and walked over to get it, although her mom thought it was because Angelica wanted to hug her. After Charlotte picked Angelica up, Angelica took the cookie from the other baby and ate it.
After hearing that, the babies try getting Dil to walk for a carrot that Chuckie had left over from a snack he had earlier, but Dil doesn't want it.
Phil and Lil started walking after they had apparently gotten into a fight, but their mom thought that they were helping each other to walk.
Hearing that, Lil pretends to be Dil's twin sister to try and get him to start walking, but it doesn't work.
Chuckie didn't actually walk the first time. He ran. He was in the front yard with his dad, and he got scared when he saw this giant Clown-head on top of an ice cream truck that was coming towards his house, but Chas thought it was because he just wanted an ice cream treat.
Hearing that, the Rugrats (mainly Angelica) decide to scare Dil into walking, but Tommy stops them and tells them that Dil won't start walking until he's good and ready, and Dil's shown to be happy that Tommy's standing up for him.
While this was going on, Stu was setting up motion-activated video cameras that would start recording if Dil walked. Didi ends up rushing home after receiving the call from Stu that Dil was walking and knocks over the cameras. In the end, the adults realize that Dil really is too young to start walking. As the babies are walking into Tommy's house,  Chuckie points out that they never found out what made Tommy walk for the first time.

It's revealed that Chuckie's the whole reason Tommy started walking in the first place:
Tommy remembers that Chuckie had come over to his house with Chas (this was after Chuckie started walking), and remembers that he really wanted to play with Chuckie, so he pulled himself up using the back of the couch in the living room and started walking.
Chuckie's touched by the fact that he was the reason Tommy started walking. After Chas tells Chuckie and Kimi that they're leaving, Dil sees Tommy walking with his friends and tries getting up to start walking the way Tommy did the first time, but he's unable to do so. Tommy comes over to Dil and tells him that it's okay that he's not walking yet and that he can still play with Dil, which makes Dil happy.

Charlotte answers her cell phone while drawing a picture of a duck on her PDA. She tells her assistant Jonathan to get to her house as soon as possible, as working at home and watching the babies isn't easy for her. She then tells him that Angelica will be happy to help him watch the babies.

Downstairs, Angelica, who has a brand-new Cynthia Dream Yacht, angrily orders Tommy, Chuckie, Phil, Lil, and Kimi not to touch, look at, or even think about touching or looking at anything, most especially her new Cynthia Dream Yacht, while she's away at preschool. When Tommy asks her why not, she sarcastically asks him if he still going to ask that, and angrily tells him that he and his friends are a bunch of dumb babies. Charlotte overhears this, and when Angelica sees her, she pretends to be nice to the babies by saying she loves them very much while hugging Lil. Charlotte tells Angelica that if she catches her being mean to the babies again, she's returning her new Cynthia Dream Yacht to the toy store. Angelica is shocked when she hears this. Just then, there is a knock at the front door. Jonathan arrives, with a stack of files in one hand and a colossal low-fat no-foam cappuccino in the other. Charlotte angrily tells him that she ordered a non-fat foam-foam frappuccino. She then turns to Angelica and reminds her to be nice to the babies, like she usually is. Angelica twitches in fear upon hearing this, and Tommy tells her not to worry, as being nice to him and his friends is easy for her to do. He tries to demonstrate by saying nice things about her, but he can't think of any, and neither can Phil and Lil. Kimi tells Angelica that she has nice ponytails, and Tommy praises her for it. He then tells Angelica to say something nice about him and his friends. Angelica struggles to do so, but is interrupted by Jonathan, who tells her it's time for her to go to preschool. Angelica is relieved to hear this, as now she doesn't have to be around the babies, let alone say nice things about them, for several hours.
