Medusa

A digital equalizer displays fluctuating bars across frequency bands labeled DISCO, ROCK, POP, DANCE, and CLASSICAL. The scene cuts to SpongeBob SquarePants dancing underwater with a jellyfish, then transitions to a green-tinted scene where he dances with the jellyfish, followed by a composite image overlaying the equalizer on the dancing characters, and finally returns to SpongeBob dancing with the jellyfish in a blue environment.
