Nickelodeon has unveiled the first trailer forHey Arnold! The Jungle Movie. While it’s definitely a nice boost of nostalgia, despite noticeable updates to the voice cast and animation style, the trailer falls into the all-too-common trap of giving away far, far too much of the story. Keep that in mind before taking the plunge.

Co-written and executive produced by the TV series’ original creatorCraig Bartlett,Hey Arnold!: The Jungle Moviewill answer the question of what happened to Arnold’s parents. To do this, the movie will take the kids of P.S. 118 on a field trip to the jungle where adventure (and romance) awaits!
