Hey Arnold!
Starting in 1996 and running until 2004, Hey Arnold is a classic show for all 90s kids. The show is centralized around the main character Arnold. The fourth-grader isn't exactly the coolest kid on the block, but he sure has a lot of good friends. He lives with his grandparents in an inner-city apartment, and many of his adventures center on life as a kid in the big city, as well as school endeavors...
ChalkZone
Imagine drawing your own perfect world. That's exactly what student Rudy does when he finds a magical piece of chalk. Rudy draws portals with his magic chalk that allows him to enter another world: the Chalk Zone (2002). He can draw characters that come to life, like his best friend Snap, who is a blue robot-looking drawing who accompanies him in the different worlds.
