Everyone, meet Dedf1sh. Previously a promising, up and coming DJ, her pursuit of breakbeat perfection eventually led her to a subterranean test facility, where she was "sanitized." Though little of her former self remains, she continues crafting DJ delicacies, and the halls of the test facility echo with her bumping tracks to this very day.
Dedf1sh is a musician in Splatoon 2 whose songs were released as part of the Octo Expansion. Once a normal Octoling, she entered the underground test facility and became sanitized, losing her free will.[2]
Before the release of the Octo Expansion, a video entitled 'Catalog Mix' featuring short sections of some of the songs was made available.[3] It includes several songs heard in the Octo Expansion and its missions. The only song that was named prior to Octotune's release was Splattack! (Octo).
Trivia
In her album art, Dedf1sh uses a series of turntables each with the number 8 on them and eight buttons, corresponding to an octopus' number of arms and the overall recurring number eight through the Octo Expansion.
