Hey Arnold! Season 4 Episode 1, titled "Arnold's Halloween," is an exciting and spooky Halloween-themed episode.

The episode begins with Arnold and his friends excitedly discussing their Halloween plans. Gerald and Arnold decide to dress as an elephant and a mouse, respectively, and the group makes plans to visit a spooky old abandoned train station for some thrills.

However, things take a turn when Arnold's Grandpa Phil tells the kids about the legend of "the ghost of the train station," a terrifying figure who supposedly haunts the abandoned building. Arnold is skeptical, but his friends are spooked and decide to skip the train station in favor of other, safer Halloween activities.

Arnold, however, is determined to investigate the legend of the ghost of the train station and convinces his friend Brainy to come with him to investigate. They sneak into the train station after dark, armed with flashlights and their own sense of adventure.

As they explore the decrepit train station, Arnold and Brainy begin to see strange things: eerie shadows, creepy sounds, and even what appears to be a ghostly figure lurking just out of sight. Despite their fear, Arnold and Brainy press on, determined to uncover the truth.

Meanwhile, back at home, the rest of Arnold's friends start to worry about their missing friends. They begin to wonder if Arnold and Brainy have gotten themselves into trouble and set off to find them.

As Arnold and Brainy continue their investigation, they stumble upon the truth behind the legend of the ghost of the train station: it's all a hoax perpetrated by an old man looking to scare kids away from the abandoned building. Initially disappointed that the ghost wasn't real, Arnold and Brainy soon realize that the real excitement and thrill was in their exploration and investigation. They return home victorious, with a great Halloween story to tell their friends.
