- Stephanie being left out of the fun in "Welcome to LazyTown". She then walks, alone, singing a sad song:Have you ever been sad?
Have you got a friend who'll stay?
Have you ever been lonely?
All I want is just to play. - Stephanie's left out again in "Dear Diary" when Robbie Rotten writes mean things about Trixie and her other friends and leave it for her to find. When Stephanie arrives, everyone ignores her and she leaves.
- Also in "Dear Diary," the moment when Robbie reads what Stephanie's written about him. For all her talk about his schemes and bad habits, Stephanie ends the entry by saying that Robbie isn't really a bad person, and is a bit of a softie deep down. Robbie is at first stunned, then offended... and then stunned again when he realizes that he can't bring himself to go through with hurting Stephanie after reading her kind words. He then gives the diary back and owns up to what he did.
Robbie: Maybe I am a big softie... - In "Lazy Scouts", when her friends refuse to listen to her warnings that Robbie Rotten is not a true Scoutmaster, Stephanie leaves in a huff and returns home before lying on the bed sadly. The fact that she has her arms in front of her face without making a sound makes it hard to tell if she's crying or not. Thankfully, Milford and Sportacus console her shortly afterwards.
- A minor one in "Dancing Duel" occurs when Milford announces Stephanie as the next performer after Rottenella, Stephanie tries to give up because of Robbie Rotten's compliments on Rottenella, almost to the point of tears. Thankfully, Sportacus then comforts her and the show goes well.
- "Birthday Surprise" has everyone argue, with Robbie inciting it further to the point where Stephanie and her friends go their separate ways and don't want to speak to one another. Stephanie sings We Will Be Friends
in the hopes they can reconcile, even though she knows nothing lasts forever. - "Dancing Dreams" has Robbie trick Stephanie into going to a famous dance school far away, leading to a tearful goodbye and farewell presents from each of her friends, including Sportacus.
- "Roboticus" has the titular robot replace Sportacus as town hero, and the kids are devastated when Robbie says he'll have to leave town, especially Stephanie and Ziggy.
- The first and the last songs sung by Mayor Meanswell in the 1996 play, as he laments the state of the town and ultimately gives up on saving it.
- Alveg ein, Trixie's solo song from the 1999 play when she's locked in jail for something she didn't do.
- "Aleinn um jólin" from the Latabae Christmas album, a song where Glanni Glaepur is tempted by the warmth and love of Christmas as he's alone in the cold, but insists he's fine being alone and miserable. Icelandic singer Kristján Kristjánsson sings as a counterpoint to try and get him to change, with songwriter Máni Svavarsson saying he represents Glanni's conscience. The song was also the last public performance Stefan Karl Stefansson made before he died.
- From the same album, Trixie's solo song, Ég á mér ósk, which is about how she's certain she won't get anything for Christmas—so all she wants is for people to understand one another, get along, and love one another. Thankfully, she does get presents from the cast.
- From the same album, Trixie's solo song, Ég á mér ósk
- "LazyTown Forever" is a fandom passion project that features the vocals of Chloe Lang and is produced by the show's musical producer as a Grand Finale song for the series as a whole, celebrating everyone that worked on it, watched it, and kept it going in their hearts. The final section - which samples a Robbie Rotten line from "The First Day of Summer" where he states that he misses the LazyTown gang - especially takes a whole new meaning after the death of Stefan Karl Stefansson in 2018.
- In an AMA session, Stefan Karl revealed what Robbie truly thinks of the other characters, deep, deep down: "I wish I could be their friend." Ouch. It's worse when you consider that some episodes indicate that the others do view him as a friend, in their own, weird way. As Stingy puts it, he's a pain in the neck, but he's their pain in the neck. But Robbie doesn't see it.
