7. Hey Arnold!
Arnold was a typical fourth grader who lived with his grandparents in the boarding house they owned. Each episode focused on Arnold as he tackles city life and other childhood problems. Like every young kid, Arnold also has an admirer in the form of his classmate Helga. This is due to Arnold being the first person to be nice to Helga when they were younger though Helga doesn't tell Arnold how she feels- instead she writes poetry and collects bits of his used gum to add to her Arnold Shrine.
