The eels are drawn to music, traveling toward any tune they catch. That fondness is exactly what brought them to the surface when the Straw Hat Pirates struck up a performance.

History

One day the Straw Hat Pirates tried playing music as a way to lure fish, and partway through the set the music-loving brothers arrived. Once the eels swam off, the crew remarked on how uncommon such a sighting is. Luffy wished he had managed to eat one, and Nico Robin guessed they would taste wonderful, a claim that has never been put to the test.
