(For the sake of this story being something that can relate to everyone, I will be keeping Agent 3's identity and appearance unknown since they are a player character.)
A group of Ringed Octolings finally reached the place in which Inklings were captured, once they found them, they didn't hesitate to break the glass prison keeping the Inklings trapped. They then evacuated the facility while Coral and Kelp continued on to find the master control, hoping that they would be able to shut it down before Clam and the rest of the Tentacle Troop get brainwashed, thankfully, the Tentacle Troop hearing the song that Rebekah sung actually bought time for Coral and Kelp to shut down the facility and stop the brainwashing waves being emitted from the inside. Once they found the master control area, Kelp called the General.
Kelp: *Calls Anemone* We found the master computer, what should we do?
Anemone says "I will send out a rescue squad, but since they are Octocopters, they are going to take visual and sound clues and stay farther from the facility until I give them further orders." Coral then starts working on the central control computer to shut the facility down, after the screen displays the shutdown + the self-destruct sequence. He activates that sequence, causing the entirety of the facility to shut down followed by a self-destruct sequence starts with the clock starting at 2 minutes. It is then at this time that the brainwashing wave stopped being emitted, allowing the entirety of the Tentacle Troop become relieved and escape the facility, the Ringed Octolings following them, except for Coral and Kelp since they wait for the rescue squad. Conversely, all the tentacle Crimson Octarians come to their senses and escape the facility with the Crimson Octolings who were brainwashed following them. It's at this time that the rescue squad destroys the ceiling of the room in which Coral and Kelp are in right now, carrying a platform in which Coral and Kelp gets on. The rescue squad waits for anyone else who might not be able to escape the facility before it explodes.
