The song's lyrics describe a beach party while mentioning both real and imagined marine animals ("There goes a dogfish, chased by a catfish, in flew a sea robin, watch out for that piranha, there goes a narwhal, here comes a bikini whale!"), with absurd noises accompanying each, provided by Kate Pierson on the higher-pitched sounds and Cindy Wilson the lower-pitched ones. The chorus features Pierson and Wilson singing a long "ahhh" at an ascending pitch, followed by Schneider exclaiming the phrase "rock lobster!".
