Big Betrayal is a song performed by Deep Cut. It is one of four songs that can play during Splatfest battles in Splatoon 3, added into rotation during Drizzle Season 2023 and first being used in the Shiver vs. Frye vs. Big Man Splatfest.


Big Betrayal is a midtempo EDM track with elements of house and J-pop. The first half of the track is in the key of A minor, opening with a lighter chord progression that revolves around the v and bVI (E minor and F major) with synth leads panned left and right that resemble sirens. This transitions into the section in which Shiver and Frye harass Big Man in the music video, with electric bass and synthesizers that share a unison bass line. When the sung vocals begin, the song modulates to Bb minor, with Shiver and Frye singing hits along with the instrumental backing. The chorus comes in after a 1-bar break with the idols harmonizing with a vocoder to a punchy, syncopated melody and is followed by a halftime section similar to Till Depth Do Us Part that loops into the intro.

Big Betrayal contains two verses, both sung to the same music.

Big Betrayal features production techniques that are not often heard in Deep Cut's vocal tracks, such as sample splicing and abrupt cuts in the backing track, which are more prominent in their non-vocal tracks such as Deep Cut's Theme and Surprise and Shine.

Big Betrayal Lyrics (Romanized & translated by Nintendo of America)

F (translation):Yo, Big Man. Wanna explain this photo?
'Cause it looks like a thoughtless,
careless chump...
cozying up to those Inkopolis sisters!

B (translation):Ay! Ay! Ay-
(No, no, no! That's just Ian BGM!
Uh- I think he's a vocalist of
no relation whatsoever-)

F (translation):You think we're that dumb?!

S (translation):Awww, don't worry.
It's nice to see you having fun
with new friends.
Maybe you should
spend ALL your time with them
if they're so great!

B (translation):Ay- Ay... AY! (Alright, listen- It's just-
I want artists from Splatsville and
Inkopolis to get along!
And I thought that doing a collab would-)

S (translation):You wanted a collab?
Well, I want cold, hard cash!
Next time we get a piece, capisce?

  • Each idol's main concerns as expressed in the translated argument portion of the song reflect the stances they held in the Money vs. Fame vs. Love Splatfest.
    • Shiver is concerned with Big Man making money without giving his bandmates a cut, in alignment with her representing Team Money.
    • Frye is concerned with Big Man's association with the Squid Sisters damaging Deep Cut's reputation amidst Inkopolis and Splatsville's ongoing rivalry, in alignment with her representing Team Fame.
    • Big Man is concerned with helping build friendly relations between Inkopolitan and Splatlandian musicians through music collaborations, in alignment with him representing Team Love.
  • This is one of the few songs to include a word from a real language in its lyrics, namely the phrase "pishagerudo" (ピシャゲルド), which is part of the Japanese name of the song.


Big Betrayal is a reference to Big Man's involvement in the production of Liquid Sunshine with the Squid Sisters without informing Shiver and Frye, who see this as a betrayal of Deep Cut. "Big" in the name might refer to Big Man.
