Happy Days Cast Guest Star On SpongeBob SquarePants

Happy Days star Henry Winkler, who played Arthur "The Fonz" Fonzarelli, and Michael McKean and David Lander, who played Leonard "Lenny" Kosnowski and Andrew "Squiggy" Squiggman on its spin-off, Laverne & Shirley, lend their voices in a brand-new SpongeBob SquarePants episode, airing this Wednesday.

In the episode, "The Sharks" are the toughest guys in town, but their next confrontation might be too much for SpongeBob to handle. Henry Winkler voices Sharkface, a tough guy who grew up on the mean streets of Bikini Bottom; Michael McKean voices Lonnie, a skateboarding punk from the Red Hook neighborhood of Bikini Bottom; and David Lander lends his voice as Donnie, a guy who grew up in an upper-class family in Bikini Heights.

Check out a sneak peak from "Sharks vs. Pods" in the video below.

"Sharks vs. Pods" episode of SpongeBob SquarePants will premiere Wednesday, May 4, at 5:30pm (ET/PT) right after a new episode of Nickelodeon's newest animated comedy series, The Loud House.
