SpongeBob SquarePants is an American animated television series. Much of the series is centered around the exploits and adventures of the title character and his various friends in the underwater city "Bikini Bottom". The series' popularity has prompted the release of a media franchise, contributing to its position as Nickelodeon's highest rated show, the most distributed property of MTV Networks, and among Nickelodeon's most-watched shows.
Lori Alan, who voiced Diane Simmons on Family Guy, voices Pearl Krabs on the show. Adam West voiced a young Mermaid Man in the episode "Back to the Past".
In "Road to Rupert", after Peter Griffin has lost his driver's license, and his daughter, Meg, has volunteered to drive him around, she becomes annoyed by Peter's childish behavior. To distract him she puts in a SpongeBob SquarePants DVD, which includes the camping episode in which SpongeBob and his friend, Patrick Star, sing the "Campfire Song Song", a SpongeBob SquarePants episode directed by "Road to Rupert" director, Dan Povenmire. SpongeBob and Patrick are voiced by Tom Kenny and Bill Fagerbakke, respectively, reprising their roles.
Also, in several episodes, a greenish version of SpongeBob is one of Stewie Griffin's toys. He was used as protection against the tooth fairy in "Prick Up Your Ears" along with Starscream and Man-E-Faces.
In "Road to the North Pole", Stewie asks Brian whether SpongeBob and his friend Squidward are like Santa Claus in terms of existence.
SpongeBob is parodied as a "SpongeCow" balloon in the J.C. Penney's Thanksgiving Day Parade in "Turkey Guys".
In "Inside Family Guy", when Peter is doing a job as a Hollywood Boulevard mascot before deciding to return to Family Guy, a person in a SpongeBob costume can be seen taking photos with tourists.
