If you grew up watching Nickelodeon, then there's a very good chance that you've seen episodes of the popular cartoon Hey Arnold!
The animated series premiered in 1996, and the premise revolved around Arnold, a fourth-grader with a football-shaped head, and the different ways he dealt with living in a big city and problems he and his friends encountered on a daily basis.
Fans of the show will recall that Arnold lived in a boarding house located the fictional city of Hillwood with his grandparents, but one thing that remained a mystery was his parents' whereabouts.
The writers of the show never bothered to explain how his parents went missing during the five seasons that the show was on air, and just when fans got hopeful that they would answer that question in the 2002 Hey! Arnold movie, they were let down again.
Now, fifteen years after the last movie, a TV movie continuation of the series, Hey Arnold!: The Jungle Movie has been released, and it finally answers all the questions we had about Arnold's parents.
