Seasource is a song performed by SashiMori. It was added to Splatoon 3 as part of Sizzle Season 2024 on 1 June 2024.


Seasource roughly fits into the template of SashiMori's usual combination rock/electronic stylings. The song is described by official material as "explor[ing] new sonic ground" and is implied to be emblematic of Paul's shifting sensibilities from having aged into his teenage years since Splatoon 2 (he is specifically stated to have "had" a childlike innocence at 10 upon joining the band); it also features a female vocal sample that is stated to "[express] an innocence that transcends barriers".[1]


When he first joined SashiMori DJ Paul had a childlike innocence, but now he's 16 years old. Their latest song "Seasource" features a vocal sample that "expresses an innocence that transcends barriers." These vocals combined with a loud rapid-fire beat explore new sonic ground!

"Seasource" seems to be a portmanteau of "sea", "resource", and possibly "seahorse", and may also be a reference to Paul's method of "sourcing" SashiMori's vocals from records.
