Even though the voice of SpongeBob Squarepants, Tom Kenny, has appeared in over 20 episodes of Rick & Morty, most viewers are unaware of his involvement. Throughout the series, he's played 25+ characters including a sulfur-eating pawnshop clerk, an anthropomorphic pencil, a Nazi, a slut dragon, a pizza, an ant superhero, and a sexual predator jellybean.
The only recurring character Kenny portrays is Rick's drinking buddy, Squancy - a cat creature with a compulsion for committing lewd acts while asphyxiating himself.
