Tidal Rush is an electronic remix of both of the Squid Sisters' solo songs, adding Tide Goes Out to DJ Octavio's remix of Bomb Rush Blush. Therefore, it has very similar production to the Bomb Rush Blush remix. It begins with Marie singing the chorus of Tide Goes Out over an orchestral violin intro. She then continues to sing the chorus, but faster and in a higher key to fit with the Bomb Rush Blush remix which fades in, before eventually, both cousins sing the chorus of their respective songs simultaneously. After an instrumental break, the two alternate lines from their respective songs before both of them simultaneously sing again. Finally, Callie sings her section on her own before the track loops.

DJ Octavio is the leader of the Octarians, the main antagonist, and final boss of both Splatoon and Splatoon 2's single-player modes. In the latter, he appears alongside Callie in the final boss, whom he has brainwashed, and is trapped in a snow globe-like tank near Cap'n Cuttlefish or Marie after being defeated for the first time.
