Nickelodeon is headed back to Olmec's temple. The children's network greenlighted a live-action TV movie inspired by the iconic '90s game show "Legends of the Hidden Temple." The movie will draw from the game show's original premise of kids competing to retrieve artifacts from a mysterious Mayan temple.

The "Legends of the Hidden Temple" TV movie will follow three siblings who embark on a high-stakes, life-or-death mission and will star Isabela Moner from Nickelodeon's "100 Things to Do Before High School." Production will begin in March, but Moner first introduced her character's name on Twitter on Tuesday.

"can't wait for ya'll to meet my character, Sadie!! working on the movie right now," she tweeted.

Read the official synopsis below:

"The TV movie 'Legends of the Hidden Temple' will follow three siblings who break away from a lackluster temple tour in a jungle, finding themselves immersed in a real-life mission comprised of obstacles that they must complete in order to escape alive."

The movie will incorporate several elements from the show including Olmec, the talking head that knows all the secrets behind the temple and The Steps of Knowledge, which was the entrance to the temple and the start of the mission. The colored animals from the team names such as the green monkeys, the red jaguars and the silver snake will also make cameos.

"Legends" isn't the only '90s nostalgia that Nickelodeon will recapture this year. The network also officially gave the greenlight to a two-part animated "Hey Arnold!" TV movie, which the series' original creator Craig Bartlett will write and executive produce.

Announced last fall, the "Hey Arnold" TV movie will resolved the unanswered plotlines and storylines, including the answers about what actually happened to Arnold's missing parents.

"The greenlights for the 'Legends of the Hidden Temple' and 'Hey Arnold!' TV movies are terrific examples of how we are bringing our beloved content back to life both for new audiences and the generation that grew up on them," Cyma Zarghami, President, Viacom Kids and Family Group, said in a statement. "These TV movies will keep the spirit and essential themes of the original source materials intact, while branching out in new ways that will speak to and captivate today's kids."

Both TV movies will premiere in 2017.
