In the Hanna-Barbera adaptation, Irona's bodyguard function is rather charming. The moment she receives a distress call from Richie, she will react, "Uh-oh, Richie's in trouble!" She instantly goes into jet plane mode and launches while yelling, "I'm coming, Richie!"
In one comic book story, Richie's having a hard time coming up with something to get as birthday gift for his dad, especially considering his dad is someone who, quite literally, has everything—in the end, Richie invites his dad to come with him to a baseball game. In the final frame, Richie hears his father on the phone with a friend. His father is breaking down crying, telling the friend that his son gave him the best birthday gift he could imagine.
In another comic book story, Richie caught measles, so the doctor places him and everyone else at Rich Manor in quarantine for the following week to prevent the disease from spreading and that includes Freckles and Pee Wee Friendly, who were visiting Richie when the doctor gave his diagnosis. As the week passes, Mr. and Mrs. Friendly become afraid that, after one week with the luxuries of Rich Manor, their sons will rather stay there than return to their home once the quarantine time is over. Fortunately, once the kids return, they're too happy upon seeing their parents again to care about luxuries.
1994 Film Adaptation
Richard and Regina Rich make it clear that their vault contains childhood memories and treasures, not money or gold (the opposite of the comics).
Van Dough: Are you kidding me? You mean to tell me that there isn't a single gold bar, or emerald, or thousand-dollar bill in this entire mountain?! Regina Rich: Well, I'm sorry to disappoint you, Lawrence, but that's not what we treasure.
To enter the vault, Richard and Regina have to sing a duet in harmony, and the song they use is something they know by heart.
Better yet: The song is "Side by Side," which is about loving someone no matter how poor you are.
The mere existence of the Dad Link: no matter where Richard is in the world, Richie knows that he can contact his dad and he will respond to him, even if it's just to tell him that they'll talk about things later. This is a man who clearly values his family and, most importantly, his son.
Throughout the film, Richie and his family are shown to be nothing but Nice to the Waiter toward every single one of their servants. An early scene with young Richie shows him saying "thank you" to his butler and treating Cadbury and the others with absolute respect.
The ending where Richie is playing baseball with his new friends, and his parents call him truly the richest boy in the world because he's finally got something that money can't buy: real friends.
