Whenever he sees someone in trouble, Arnold goes out of his way to help them out, even if it is not sensible to do so.
Appearances in Christmas specials
Arnold's only starring role in a Christmas special was, naturally, the Hey Arnold! episode "Arnold's Christmas". In it, he is assigned to be the Secret Santa for his fellow boarder, Mr. Hyunh, whom he notices is always depressed around Christmas time. When he talks to Mr. Hyunh about what he would like for Christmas, he learns that all Mr. Hyunh wants is to be reunited with his daughter, Mai, whom he had given up to be saved by American rescue soldiers during the Vietnam War. On Christmas Eve, Accompanied by his best friend, Gerald Johanssen, Arnold goes to the Federal Office of Information to find out where Mai currently lives. The supervisor, Mr. Bailey, only agrees to help if Arnold and Gerald can do his Christmas shopping for him. They manage to do so, but are unable to find the last item on the list - a pair of Nancy Spumoni snow boots. When they tell him they could not find them, he refuses to find Mai, and Arnold goes to bed that night, feeling sad that he could not grant Mr. Hyunh's wish.
Unbeknownst to Arnold, however, his bully/secret admirer, Helga Pataki, overheard him talking about how he wanted to make his Mr. Hyunh happy, and she has just received a pair of Nancy Spumoni snow boots from her mother. She comes to realize that making Mr. Hyunh happy is exactly what would make Arnold so, so she gives up her boots to Mr. Bailey and gets him to locate Mai. When she arrives at the boarding house on Christmas morning and reunites with her father, Arnold is pleasantly surprised and puzzled as to how this miracle happened.
Other Christmas productions
Arnold also appeared along with Gerald and Helga in the Merry Nickmas interstitial shorts. They are shown in stop-motion animation in "The 12 Days of Nickmas", where they sing the line "Three cans of hairspray."
