Trivia

 * Before the actual song was revealed by Nintendo, the Squid Sisters' dance animations for Tomorrow's Nostalgia Today were datamined in the 3.0.0 update of Splatoon 3. There were no audio files attached to it, however, and the song would not play when the animations were hacked into the game.
 * In-universe, the lyrics of this song were written by Callie, with the message of how much better Inkopolis has become in the years since the original.
