"Q U A D R I N O M E T R Y – THE SECRET OF THE WAVE LIES IN C R E A T I O N" is an instrumental song that plays in "Ocean Gem". Greg plays the instrumental in his van; it was one of Rose Quartz's favorite instrumentals, but it is also one of Garnet's (and by extension Ruby and Sapphire's) least favorite instrumentals to the point it convinces Garnet to jump out of Greg's moving van when the tune plays.

- The Gems' individual reactions to the instrumental descend negatively:
