Jill Talley provides the voice for Karen, the snarky, computer-screen wife of Plankton, who is the perennial villain of the series. This means that the voice of the cheerful, oblivious SpongeBob is married to the voice of the main antagonist's spouse, creating a hilarious dynamic both on and off-screen.

The Many Voices of Bikini Bottom

In SpongeBob SquarePants, Kenny doesn't just voice the main character. He also provides the voice for SpongeBob’s beloved pet snail, Gary, whose meows and purrs are instantly recognizable. Furthermore, he voices the French Narrator, Patchy the Pirate, and a host of minor, recurring characters.

Iconic Roles Outside of Bikini Bottom

Kenny's vocal range is truly staggering, encompassing some of the most memorable characters in modern animation. His other most famous roles include:

• Ice King from Adventure Time

• Heffer Wolfe from Rocko's Modern Life

His ability to switch between the manic energy of SpongeBob, the pathetic loneliness of the Ice King, and the deep, booming voice of the Narrator showcases a masterful command of his craft.

3. The SpongeBob Voice Was Based on a Real Person

The high-pitched, nasal, yet cheerful sound of SpongeBob is not just a random cartoon voice. It was inspired by a specific character voice Tom Kenny developed early in his career, and the character's personality was crafted by the show's creator, Stephen Hillenburg.

The Origin of the Iconic Laugh

Kenny has mentioned in interviews that the voice originated from an early, unused character he created. The unique, high-pitched laugh, which sounds like a dolphin's squeal mixed with a creaking door, is what truly defines the character.

Series creator Stephen Hillenburg, a marine biologist and animator, conceived the character as a "childish, responsible, joyful, and clumsy sea sponge." Hillenburg specifically chose Kenny for the role because of his work as Heffer Wolfe on Rocko's Modern Life, where Hillenburg was a director.

Kenny’s voice, combined with Hillenburg’s vision, was the perfect marriage of sound and character design, creating a global phenomenon that has endured for decades.

4. The Rest of the Bikini Bottom Main Cast is a Voice Acting Dream Team

While Tom Kenny is the star, the success of SpongeBob SquarePants is built on the chemistry of its core ensemble, a group of veteran voice actors who have worked together for over 25 years.

• Rodger Bumpass as Squidward Tentacles
• Clancy Brown as Mr. Krabs
• Carolyn Lawrence as Sandy Cheeks
• Doug Lawrence (also known as Mr. Lawrence) as Plankton and Larry the Lobster
• Mary Jo Catlett as Mrs. Puff

This group of actors, many of whom are also comedians and writers, are masters of their craft, ensuring the show maintains its high level of humor and character consistency across hundreds of episodes and multiple movies.

5. Tom Kenny is Excited About SpongeBob's Enduring Legacy into 2025
