- Kenny wishing to reverse everything that happened, giving up his chance at being brought back to life."Goodbye, you guys."
- Later on, we're given a sweet scene of him shooting up into Heaven, while everyone at South Park, including his parents, all happily wave goodbye to him, as pictured above.
- Stan and Wendy making up at the end.
- Sheila apologizing to Kyle at the end.
- Plus, when Kyle reminds her that it was Cartman's "fucking filthy mouth" that saved them, she didn't go nuts like she would have.
- Sharon and the other mothers quitting the M.A.C. to help their kids. Doubles as a Moment of Awesome.
- Kenny's conversation with Satan.
- La Resistance gathering around Terrance and Phillip to stop the military and Kyle's mom from executing them. Also counts as a Moment of Awesome for Kyle for standing up to his mom. Unfortunately, she doesn't listen.
Kyle: I don't want a fighter, I want my mom.
- Terrance and Phillip appear be to quite taken aback by the gesture themselves.
- Sheila patting Terrance and Phillip on the shoulder during the reprise of "Mountain Town" at the end.The Mothers: (singing) Cause Terrance are Philip are sweet.Sheila: (hugs the brothers) Super Sweet!
- When Kyle hides Ike in his attic, he makes a promise to Ike to stop all the madness, get their mom to come home and become a happy family again.
- Kyle's Armor-Piercing Question to his mother, reminding her that her own adopted son is Canadian. This and the above moment each show that Kyle does care about Ike in spite of how he treated him at the beginning of the movie.
- A blink and you'll miss it one, during the La Resistance musical number, Kenny's dad has a picture of him on his helmet.
- "Through the Eyes of a Child", the last end credits song. It pulls off the seemingly impossible feat of being a tongue-in-cheek Award-Bait Song parody that retains the wit of South Park while still having a poignant melody and lyrics (about the innocence of children, or lack thereof).
- In the middle of the American/Canadian battle field when things look incredibly grim, Cartman takes the time apologizes to Kyle for ripping on him for being Jewish. It's ruined due to Cartman Comically Missing the Point, telling Kyle that he's actually not a Jew but let's face it, with Eric Cartman that's the closest thing to a heartwarming moment you're going to get.
- A fridge heartwarming moment: who did they get to voice Kenny? Mike Judge, creator of Beavis And Butthead and King of the Hill. Matt and Trey insisted on paying tribute to one of the pioneers of adult-oriented animation.
- An incredibly sweet behind-the-scenes example, that overlaps with Tear Jerker: while Sheila starts a war against Canada over a cartoon, her voice actress, Mary Kay Bergman, was close friends with Canadian-born Tara Strong, and even gave her a dog for her 26th birthday, four months before the movie came out. And then she died five months after the movie came out.
- Another meta-example: with massive Executive Meddling from Paramount and the MPAA and interest in the show waning after only the second season, Trey Parker was convinced that the film would be a major flop and made it as a last hurrah for the series and his career. Instead it was a commercial success and critically acclaimed as a smart and funny satire, establishing the show as one of the most beloved shows of all time, even in its 22nd season, and also established Trey, along with Matt, as one of the most loved cartoonists of all time.
