Kamp Koral: SpongeBob's Under Years

Kamp Koral: SpongeBob's Under Years (often shortened to Kamp Koral) is an American animated series that debuted on Paramount+ on March 4, 2021. A prequel and spin-off of Stephen Hillenburg's SpongeBob SquarePants, it centers on younger versions of the main characters attending a summer camp. The show was developed by Luke Brookshier, Marc Ceccarelli, Andrew Goodman, Kaz, Mr. Lawrence, and Vincent Waller.

The idea for the series came from flashback scenes in the 2020 film The SpongeBob Movie: Sponge on the Run. In October 2018, shortly after becoming Nickelodeon's president, Brian Robbins assembled a team to brainstorm potential SpongeBob spin-offs. A spin-off was reported in February 2019, and in June 2019, Kamp Koral was officially announced with a 13-episode first season, later expanded to 26 episodes in March 2021. A second 13-episode season was ordered in August 2021 and premiered on Paramount+ on July 10, 2024.

The show follows a 10-year-old SpongeBob SquarePants at a sleepaway camp run by Mr. Krabs, a single father raising his baby daughter Pearl. Scoutmaster and arts-and-crafts teacher Mrs. Puff oversees camp activities. SpongeBob shares a cabin with friends Patrick Star and Sandy Cheeks, supervised by Squidward Tentacles, a pessimistic junior counselor slightly older than the others. Meanwhile, chef Plankton operates a secret laboratory beneath the camp with his computer assistant Karen, plotting world domination. Episodes focus on the campers learning about the campsite, exploring new areas, and enjoying summertime activities.

Characters include SpongeBob (voiced by Tom Kenny), Patrick (Bill Fagerbakke), Squidward (Rodger Bumpass), Mr. Krabs (Clancy Brown), Sandy (Carolyn Lawrence, shown with braces), Plankton (Mr. Lawrence), Mrs. Puff (Mary Jo Catlett), Karen (Jill Talley), and baby Pearl (Lori Alan). Two hillbilly narwhals, Nobby and Narlene (voiced by Carlos Alazraqui and Kate Higgins), live nearby, and a camp counselor named Kidferatu is the child version of Nosferatu.

Originally slated for a July 2020 Nickelodeon premiere, the series was moved to CBS All Access (later Paramount+) in early 2021, with Nickelodeon airings following later that year. The first six episodes launched alongside The SpongeBob Movie: Sponge on the Run on March 4, 2021, with Nickelodeon airings beginning April 2, 2021.
