If the image of a young Kenan Thompson wearing flippers and speaking bad French in a bubble bath elicits waves of nostalgia, you’re probably a child of the ’90s.

Same if you know Kel Mitchell as a well-meaning but incompetent fast food worker, or Lori Beth Denberg as a hypocritical librarian who howls at children to be quiet while causing a constant ruckus.

These absurdist characters from the children’s sketch show “All That” were beloved ’90s oddities that could thrive only on cable . From its debut in 1994 to its cancellation in 2005, “All That” was a cultural force in kids’ television, a PG version of “Saturday Night Live” that became known for churning out young talent. The Nickelodeon show helped launch the careers of Thompson, Amanda Bynes, Nick Cannon and Jamie Lynn Spears, while spawning hit shows such as “Kenan & Kel” and “The Amanda Show.”

Now, 25 years after it first launched, Nickelodeon is rebooting “All That” with a new batch of child actors. Thompson, the cast member who has perhaps found the most success as an actor, signed on as an executive producer. The network has marketed the reboot, which airs on Saturday night, as the triumphant return of popular characters like Mitchell’s “Good Burger” cashier and Denberg’s “Loud Librarian.”
