For the pilot of SpongeBob SquarePants, Tom Kenny has recalled, Stephen Hillenburg brought a tank of helium into the recording studio. Kenny never needed it. The voice he built instead, which he describes as “a Stan Laurel, Jerry Lewis kind of child-man”, has outlived its creator and now anchors a franchise of films, spin-offs and specials that Hillenburg said he did not want. That is the odd position Kenny occupies: the most constant element of a property whose shape he does not control.

Kenny grew up in Syracuse, New York, the city where he was born, and went to Bishop Grimes, a Catholic junior and senior high school. His comic education started earlier than that. In first grade he met Bobcat Goldthwait, who became a lifelong friend, and the two later worked open-mic nights as “Tomcat” and “Bobcat”, a nod to the comedian Barry Crimmins.

Stand-up came first and lasted about eight years on the road. Film arrived in small doses, among them a part in Shakes the Clown, Goldthwait’s 1991 comedy about an alcoholic children’s clown. Television gave him two ensemble jobs that shaped him: the Fox sketch show The Edge, where he met the actress Jill Talley, and HBO’s Mr. Show with Bob and David, the alternative-comedy laboratory run by Bob Odenkirk and David Cross.

The turn to voice work came through Rocko’s Modern Life, where Kenny played the steer Heffer Wolfe and where a former marine-biology teacher named Stephen Hillenburg was working as a writer and director. By the late 1990s Kenny was one of the busiest voices in American animation, playing Dog in CatDog and both the Mayor of Townsville and the narrator in The Powerpuff Girls. Hillenburg approached him in 1997 about the lead of an undersea pilot. The series premiered on Nickelodeon on May 1, 1999, with Kenny also voicing Gary the snail, the French narrator and, in live action, Patchy the Pirate.

The sponge never boxed him in. He was the Ice King in Adventure Time, a princess-snatching wizard whose comic villainy the series slowly revealed as grief and madness, the Penguin in The Batman, Starscream in Transformers: Animated and Spyro in the video games from the second instalment onward. The prizes followed the voice rather than the face: Annie Awards in 2010 for SpongeBob and in 2014 for Adventure Time, and Daytime Emmys for SpongeBob in 2018 and 2020.

The harder part of the story begins with Hillenburg himself. He gave up running the show after the first feature because he wanted it to end before it jumped the shark; Nickelodeon kept it going. Asked about spin-offs, he answered that Patrick on his own “might be a bit too much. So I don’t see any spin-offs.” After Hillenburg died of ALS in November 2018, the network announced a slate of them anyway: a prequel about SpongeBob’s childhood, a talk-show vehicle for Patrick, streaming features built around Sandy and Plankton. Paul Tibbitt, a former showrunner, called the prequel idea “greedy, lazy executive-ing”. Kenny voices SpongeBob in all of it, and the criticism of the expansion rarely reaches him. It should be said plainly why that matters. His performance is the one element that makes the newer material feel like the original, so the most faithful thing about the franchise is also what lends credibility to the parts its creator rejected.

None of that has slowed the work. In February 2024 Kenny and Bill Fagerbakke, the voice of Patrick, appeared on Nickelodeon’s alternate broadcast of Super Bowl LVIII as their characters, improvising through motion capture. Netflix released Plankton: The Movie in 2025, and that December Paramount opened The SpongeBob Movie: Search for SquarePants, Derek Drymon’s pirate adventure with Mark Hamill as the Flying Dutchman. It grossed about $169 million worldwide on a $64 million budget and earned the franchise’s best CinemaScore, while The New York Times faulted what it called a “cynical philosophy of children’s entertainment”.

This year he went back to the Ice King for Adventure Time: Side Quests, a prequel of standalone episodes with a young Finn and Jake whose second season premiered in early October. In February NPR’s Fresh Air returned to its conversation with him. Music is the outlet that is entirely his: for about a decade he has fronted Tom Kenny & the Hi-Seas, a twelve-piece rock-and-soul band formed with the producer Andy Paley, which played Houston’s Continental Club on October 2. “We are on a mission from Wilson Pickett, Howlin’ Wolf and Freddy Cannon, not God,” he told the Houston Press.

Kenny, born on July 13, 1962, has been married to Jill Talley since 1996. She voices Karen, Plankton’s computer wife, in SpongeBob SquarePants, and the couple have two children, Mack and Nora. In 2022 the Syracuse Area Music Awards gave him a lifetime achievement award and a place in their hall of fame, a musician’s honour for a man most of the world knows as a cartoon.

The next dates are already set. Nickelodeon’s hour-long holiday special Merry Christmas, Mr. Plankton, in which Plankton seizes the North Pole, is due at the end of this year, and in spring 2027 Kenny returns as the purple dragon in Spyro: A Realm Beyond, the first new Spyro game in nearly two decades. Hillenburg’s sponge has become a portfolio. Its voice is still one man in a booth, no helium required.
