Hooked was one of four songs added in the version 2.0.0 update of Splatoon. Like all battle songs, it has a random chance of being played during online matches. The song features a brief, dissonant piano intro, leading into an intense piano beat backed by synth and drums. The vocals in this song are sung in the Inkling language, and are generally low-pitched. The hook features a melody first played on piano and synth, and then played again on guitar, before the song loops.
In Splatoon 2, Hooked can be unlocked to listen in Squid Beatz 2 as a final reward from the Inkling Squid amiibo. It cannot, however, be heard anywhere else in the base game. It has a maximum score of 223 and 285 in Normal and Hard modes, respectively.
- Strangely, this song, alongside Sucker Punch, features a prominent synth, despite in-universe band Hightide Era featuring no synth player.
Hooked can be interpreted as a double-meaning, one referring to being addicted to something, and the other being a reference to fishing hooks, and how fish that fall for bait are "hooked" themselves.
