Facebook is supposed to be only for people over 13, but the kids' series about a porous, absorbent yellow sponge who lives in a pineapple under the sea has accrued more than 46.5 million Facebook fans, nearly a quarter of whom are based in the U.S.

Nickelodeon has reunited the voice cast of SpongeBob SquarePants for a prequel to the series and has greenlit a live-action movie based on its animated series The Loud House as part of its 2020-21 content slate.

The kid-focused cable network has also ordered a live-action series set in space, a Henry Danger spinoff and an animated series based on the best-selling Big Nate books, along with renewals for mainstays Paw Patrol and Blaze and the Monster Machines and additional episodes of sketch-comedy series All That.

The roster is the second for Nickelodeon under the leadership of Brian Robbins, who took over the network in fall 2018 and is now president of ViacomCBS Kids & Family. The series Nick has ordered aim to expand existing franchises and launch new ones, reflect the diversity of the network's target audience and find shows families will watch together.

The new projects set for 2020-21 are:

– Kamp Koral: SpongeBob's Under Years. Ordered to series in summer 2019, the CG-animated prequel to Nick's flagship series SpongeBob SquarePants will follow 10-year-old SpongeBob to summer camp.

– The Astronauts. Nickelodeon's first co-production with Imagine Kids + Family, the 10-episode series will follow a group of kids who embark on the adventure of a lifetime when they're mistakenly launched into space. "The Astronauts stands as one of the most ambitious and cinematic stories Nickelodeon has ever told, and we are so proud to partner with Imagine Entertainment's Brian Grazer and Ron Howard, and Stephanie Sperber at their Kids + Family division, on this new series," said Robbins.

– Big Nate. Based on writer and cartoonist Lincoln Peirce's best-selling books, the animated series (ordered for 26 episodes) will center on the titular sixth-grader and his friends, with their adventures usually ending in disaster, detention or both. "With the greenlight of this show, Nate is getting one step closer to achieving true awesomeness," said Peirce.
