SPOILER ALERT!
Until now.
The newly released "Hey Arnold!" movie, which aired last week, finally reveals the answer to the mystery.
The new TV movie follows the crew as they embark on a field trip through the fictional jungles of San Lorenzo. It is revealed that Arnold's parents were victims of a type of sickness that caused them and all the adults to fall into a deep sleep.
Luckily, a cure is found and Arnold gets to return home to his parents.
Show creator Craig Bartlett told the AV Club that this ending is perfect.
"The movie’s been made to act perfectly as closure so that everybody feels satisfied that all of the storylines got wrapped up. And also, at the end of the movie, they’re starting sixth grade, so season six is also my hope."
