"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."

- Live from the Squid Research Lab

Dedf1sh is a musician in whose songs will be released as part of the upcoming Octo Expansion. Once a normal Octoling, she entered the underground test facility and became sanitized, losing her free will.

Songs
While none of Dedf1sh's songs have been named, a video entitled Catalog Mix featuring short sections of some of them has been released. It includes the background music heard in most Octo Expansion gameplay videos released so far.

The only song named is ''Splattack! (Octo)'' which is a remix of Squid Squad's Splattack when Agent 8 battles Agent 3.
