Hey Arnold! Hey Arnold! is an animated series from Nickelodeon. It was created by Craig Bartlett, and debuted in 1996. The Show Hey Arnold! revolves around 9-year-old Arnold who happens to have a football shaped head. He's a kind natured kid who loves to help out anyone who has a problem, even if it means getting too much into their business sometimes, though they do go to him for advice. He lives and goes through life in the city with his best friend Gerald, and is in fourth grade and attends PS 118. Most of the neighborhood kids never give him any problems, but Helga Pataki gives him problems and tease him all the time, though she secretly adores him. So in this show, you can get a look at everyday city life through the eyes on Arnold. / The Theme Song The Main Character / Arnold: He's just your typical nine-year-old fourth-grade (must be close to his 10th birthday then) kid...... /
