- One absolutely beautiful moment in "Music" is when Didi rocks Dil to sleep, singing "Beautiful Dreamer" all the while. This is after an entire episode of the babies trying and failing to get Dil into music and imagine stories along with it. As Didi continues singing, Dil starts dreaming of swirling lights and colors. In the last seconds of the episode, the shape resolves into an image of Tommy's face.
- Before that, Tommy's song for Dil.
- Tommy decided not to abandon Dil with the monkeys in the movie.
"My Tommy""My Dil"
- "Moving Away", the one where Angelica and her parents are moving. Angelica and the babies are all happy about it... except for Tommy, who says it's terrible and goes on to tell the story of how Angelica brought them together and it's because of her that they're friends. Angelica hears the whole story and is in tears afterwards and doesn't want to move. Probably heartwarming (IMO) because it shows Angelica's "heart of gold" side.
- Chaz, Kira, Chuckie, and Kimi being a happy family.
"Chuckie, how would you like to dance with your new mommy?"
- Specifically, the first episode after the second movie, where Kira formally adopts Chuckie as her son and Chaz formally adopts Kimi as his daughter.
- For this troper it's this one line in the second movie from Kira:
- Kira's speech to Chuckie in the episode "Changes For Chuckie"
"Hi Chuckie. Well I guess washing Wawa wasn't the best idea. You know there is still a lot about you I don't know yet. Like your favorite sandwiches or your favorite games or the songs or stories you like. Those things may take a while. What I do know is I love you very much. I hope that will do till I get the other things sorted out."
- The song sung between Tommy and Angelica during the All Growed Up TV special, as it shows clips of all the adventures they had as infants. Considering this was going to be the grande finale of the series, it was pretty poignant.
- Angelica saving the babies from Josh, also doubles as a Moment Of Awesome. "They may be just a buncha dumb babies, but they're my DUMB BABIES!"
- At the end of the first Christmas Special, a man who appears to be Santa Claus walks through the door to wish everyone a merry Christmas. He give each of the children a gift and notably asking Chucky, who had been afraid of him, if he (Santa) was still scary, to which Chucky smiled. He even gave Angelica a present who, though she had been bad, was trying to do good to make up for it. Santa told her "sometimes trying your hardest to be good is as important as already doing good". He gives her the toy she wanted but also leaves her a small lump of coal inside so she knows that she still needs to be good.
- The Rugrats second Christmas special "Babies In Toyland": The babies find themselves in a Nativity scene and think the baby Jesus is real. They feel sorry for him since they believe Santa isn't coming and he's lying alone in a pile of hay with no gifts, so one by one, they each give him their own gift just because they want his Christmas to be special. When they found him, the figure's expression was neutral. When they're done, it's smiling. Awwww to the power of 10,000.
- In the same episode, Angelica has one Imagine Spot where she visits Santa's workshop, and the elves lecture her on how mean she had been. The girl admits that she calls many people 'dumb' but never really means it; as this happens only in her imagination, it's a good view of Angelica's subconscious mind and how she actually resents her own mean ways more than once. Later, she gives gifts to all the babies, even giving Dil his very first Christmas present (a toy reindeer that Angelica was already very fond on), and a small camera for Tommy, that later becomes a very clever Fore Shadowing of his film-making dreams in All Grown Up!. So yeah, Tommy discovered what he wanted to do in life thanks to Angelica.
- "I'm a big brave dog." Whenever Chuckie comes out (inevitably nervously, and to himself) with this carefully-deployed catchphrase/mantra, a Heartwarming Moment generally won't be far away.
- The episode where the kids go to see the Dummi Bears on stage, but Angelica can't go due to a cold. The babies return, seeming to have caught Angelica's cold, but they were only faking because they wanted to be with her. Especially sweet when you remember how much Angelica bullies them. And everyone still got to see the show because Stu bought the video of it while they were there.
- Phil and Lil reuniting in "Together At Last".
- The episode "Lady Luck." Grandpa goes to bingo night at a senior home, and due to his ramblings, the babies think he's going to meet a friend called "Lady Luck." They search all over the home looking for Lady Luck, in the process, turning the soporific home upside-down and helping all the elderly visitors to have a lot of fun. In the end, the previously-tough operator of the center, seeing how much fun the seniors are having, both becomes nicer and goes out with Grandpa for ice cream.
- The end of the Mother's Day episode with the poem Chuckie's mom wrote for him.
My Sweet Little ChuckieThough I must leave you behind me,this poem will tell you where you always can find me.When a gentle wind blows, that's my hand on your face.And when the tree gives you shade, that's my sheltering embrace.When the sun gives you freckles, that's me tickling my boy.When the rain wets your hair, those are my tears of joy.When the long grass enfolds you, that's me holding you tight.When the whippoorwill sings, that's me whispering, "Night night."
- Arguably the entire episode, although special mention goes to the scenes of Tommy and Phil and Lil talking about their mums. Specifically, Tommy refers to him being in a "giant fishtank" (an incubator) and Didi comes in and holds his hand, while Phil and Lil mention that they first started laughing after they were fed "the old way" (breastfed).
- To make the latter even better, the twins comment that their first laugh is their mother's favorite memory of them.
- The episode where Susie's tricycle goes missing. She accuses Angelica of stealing it because Angelica had been mean to her earlier (which makes the assumption somewhat rational). As the episode goes on, it looks like Angelica did steal it and Susie ties her Cynthia doll to a balloon for Chuckie to let go as revenge...only for it to be revealed later that Angelica didn't steal it after all. Susie's father had moved the trike so he could paint the shed. After this, Angelica reveals she was making (well, trying to anyway) an apology card for Susie for being mean to her earlier. So we have an episode where Angelica, of all people, is apologetic. And to top it off, she does get her doll back.
- Spike sheltering a litter of stray kittens in "Spike's Babies" and the babies trying to help him.
- The ending of "Spike Runs Away." A man returns Spike, who's been missing for what appears to be weeks, late at night. Stu says they need to wake Tommy up, but Didi says it can wait til tomorrow. However, as soon as Spike hears Tommy's name, he rushes to his room and jumps on him in the crib. Tommy happily squeals "SPIKE!" as his dog licks him over and over again. Sweetest reunion between a boy and his dog ever!
- In "A Step at a Time", when the babies are recounting the time they first walked, Tommy tells them that when Chuckie had come over to his house with his dad (this was after Chuckie started walking), and Tommy wanted to play with Chuckie, so he pulled himself up using the back of the couch in the living room and starts walking. Chuckie's the whole reason why Tommy started walking in the first place.
- The episode in general counts, because Tommy wanted Dil to play with them and their walking "Follow Me Reptar". But he was also protective of Dil; while the babies were coming up with ways to motivate him (a cookie, arguing, fear of clowns) and the adults were excited of the prospect, Tommy wanted his brother to learn at his own pace. In a Generation Xerox moment, Dil sees Tommy walking by like as mentioned in Tommy's flashback, and tried climbing up to walk and play with him. He fails, but Tommy, knowing this, assures him again he doesn't have to walk and that he'll be close-by whenever he does want to play. True brotherly love.
- In "Angelica's Worst Nightmare" (where it seems like Charlotte's pregnant again): Angelica wakes up from a nightmare of her newborn sibling—in this case, a baby brother—terrorizing her and her parents totally ignoring. When her dad goes to see her, she starts breaking down and confesses to her dad that she doesn't want a new sibling and to be ignored like she was in her nightmare. Drew reassures her that he and Charlotte will always love and care for Angelica since she's their first child and she'll never ever be replaced.
- A comic strip (Whether or not it's canon to the show is debatable) showed Chuckie standing on a crack in the sidewalk. Angelica asks him what he's doing, and Chuckie says "Step on a crack, bring your mother back". Angelica is about to call him a fool because it's break your mother's back, before she realizes what he said, and then stands next to Chuckie looking up at the sky saying "See anything yet?"
- Stu saying how proud he is of Tommy in "Real or Robots?"
- Meta example: After Chuckie's first voice actress Christine Cavanaugh died in 2014, The '90s Are All That aired a marathon of episodes that centered on Chuckie in her memory.
- "Chuckie's Complaint" has a man having to wear a Reptar costume for his job. He finds it degrading until the babies come over and give him a hug, which makes him decide that his job is worth it if his presence makes children happy.
- In "The Shot," Tommy and his new friend Hector spend most of the episode terrified of getting a shot at the doctor's office; Tommy having heard horror stories from Chuckie and Angelica doesn't help. It ends up being an immense relief when Dr. Schachter turns out to be a perfectly Nice Guy. He even gives Tommy a lollipop and lets him pick his own bandage!
- The ending to the "Family Tree" episode; Stu and Didi were on a romantic cruise but Didi kept getting sick. It's not until the end that we find out why...
