"Bikini Bottom National Anthem" is the anthem that Bikini Bottomites use as a pledge. The anthem was first heard in the episode "Imitation Krabs" as part of SpongeBob and Mr. Krabs' secret handshake, and again in "Little Yellow Book" when Squidward puts it on the radio after learning he dances in his underwear when he hears that theme. The anthem was recited while SpongeBob and Robot Krabs stood on one leg and balanced a cup of chocolate milk on their heads.
- Oh, Bikini Bottom, we pledge our hearts to you.
- As faithful, as deep, as true, as blue!
- Bikini Bottom, we love you!
