Despite the impression the show, Japanese or otherwise, may give you, it contains one of the most, if not the most, touching moment I've ever seen in any anime. In the movie, The Storm Called: The Adult Empire Strikes Back, a new attraction has opened up in Kasukabe where adults can go to relive things from their past from old events to starring as characters in renditions of their favorite anime series. The leader of this group activates the nostalgic scent of the 20th century which brainwashes all the adults into coming there to stay, being in fantasy mode all the time, and abandoning their responsibilities out in the real world including their jobs and children. After a very well animated chase scene between the grunts and the Kasukabe Defense Force, Shinnosuke finds Hiroshi at a recreation of the World's Fair he'd gone to as a child, and the memory has fully regressed him to his childhood with his father and mother around. Shin uses the far more powerful scent of Hiroshi's shoes to pull him back to reality, which gives us a montage to music of Hiroshi growing up, getting his job, meeting Misae, having Shin, and leading a tough, but rich family life. It's ends with this:
Shin: "Dad. Do you remember me?"
Hiroshi: "Yes." *tearfully embraces his son* "Yes."
Every Crayon Shinchan movie has a heart warming moment. Unlike his tv counterpart, Shinchan puts himself in really risky situations to save his parents and the world. No wonder its been consistently rated as one of the most heartwarming animes in Japan and produces multiple movies that are adored by fans.
In the dub, the Nohara family give their shut-in neighbor some rice-balls and tea, along with some encouraging words, in episode 12.
When Shinchan overheard that his kindergarten teacher, Yoshinaga-sensei talking to her fiancee about quitting the kindergarten ( she's actually talking about quitting her snack time at recess so she can wear her wedding dress), Shinchan and his group decided to go to convince the fiancee at his office to not let their teacher quit, right in the school hour. It leads to a Crowning Moment Of Awesome of them riding on the train and running away from the train officer. When Yoshinaga-sensei finally caught up to them, she scolded them and they ended up tearfully beg her not to quit teaching at the kindergarten. It's a rare occurrence of seeing Shinchan crying with pure sadness and desperation.
Similarly, Shin gets asked to Pet-sit Boo's rock, and forgets where he put it after making sure to hide it somewhere safe. He winds up tearfully asking his mom to help him look for it.
In the Gag Dub, the class standing up for The Flamer when they learn he's going to be fired.
The end of the dub's Season 3 finale, in which the characters find out their show is being cancelled.
Georgie: Have you heard any news about the show's future?
Shin:Yeah, but it's bad. This is the last scene of the last episode.
Georgie: We'll fight this like we fought health care!
In one chapter of the manga, Shin and Penny/Nene see a cat attacking a injured bird and Shin ends up saving the bird by scaring away the cat with his "faceless booty alien" prank. Shin is then convinced he must take care of the bird and even his parents were surprised by this and end up helping Shin helping the bird to recover. However the animal hospital claimed that the bird isn't going to make it which devastates the family. But before the bird passes away he was briefly flying around Shin as a way of saying thanks and the chapter ends with Shin and the family mourning for the bird. Now Shin is known for being rude, showing his bare butt and "elephant", flirting with older women, but this proves that even this Japanese bad boy has a heart of gold.
In episode 19, short 3, of the original version, Misae was writing a letter to a friend and Shin-chan wrote his own letter, and the boy was sent to drop the letter at the mailbox. He waited for the mailman, and when he arrived, Shin bugged him to make sure his letter arrived to its destination. By the time it was sunset, Misae was worried and upset that her kid hasn't returned yet. Shin-chan finally arrives and rushes home, while the mailman, who was behind him finally delivers to Misae the letter that Shin wrote. What did Shinnosuke write? "Thanks for everything, Mom." Misae felt so moved after reading his son's letter.
