Ladies and gentlemen of the '90s, this is not a drill -- Nickelodeon is developing a brand-new TV movie based on Hey Arnold!, the animated series that ran from 1996 to 2004.
Before we fill you in on the details, go ahead and push play on the video below to relive the insanely catching theme song, and pull on your nostalgia-loving heartstrings.
According to Variety, who first reported the news, the movie will once again center on Arnold, our favorite fourth-grader with a football-shaped head, who lived in a boarding house with his eccentric grandparents.
The Hey Arnold! revival, which does not yet have an expected air date, will pick up where the original series ended and will resolve unanswered plotlines -- including the whereabouts of Arnold's MIA parents.
To add to your excitement, this could just be the first TV movie revival for the Viacom-owned kids' outlet. Thanks to the success of the network's Splat block of programming -- which re-airs beloved series including Rugrats, CatDog, Aaahh!!! Real Monsters, and Rocko's Modern Life -- Nickelodeon could breathe new life into many more of your childhood favorites.
