As part of the effort to revive some of its classic shows, Nickelodeon is developing a "Hey Arnold!" TV movie the picks up right where the series ended 11 years ago.

Created by Craig Bartlett, Hey Arnold! aired from 1996 to 2004, following the adventures of fourth-grader Arnold, who lives with his eccentric grandparents at their inner-city boarding house.

According to Variety, the TV movie will address unanswered questions from the series' original eight-year run, including the whereabouts of Arnold's parents.

There's no word yet about an air date.
