Alterna Space Center is located at the center of Alterna. Initially, the area is covered by a large amount of sharp fuzz and is inaccessible. After Agent 3 gathers the three treasures, they and the other members of New Squidbeak Splatoon assemble these treasures into a lawn mower-like tool, which the Captain then uses to destroy the fuzz, allowing the team to go to Alterna Space Center. However, the Captain hurts themselves in the process and the tool breaks. The members of Deep Cut then appear to make another attempt in taking the treasure back, but are told that the treasure is no longer needed and they can have it. They then help the team find Cuttlefish, who is now properly located at the top of the launchpad.
The rocket, The Spirit Lifter, is filled with Fuzzy Ooze, and Mr. Grizz plans to use it to spread the Fuzzy Ooze all over Earth. The Great Zapfish can also be seen sealed in the Steerage to power the rocket.
Both sequences feature two songs by the game's main idol group that play throughout every section except the first one and the last two.
Both sequences feature at least one song by the game's main idol group which contains a riff on "level completed" jingle (Fly Octo Fly, in reference to TEST PASSED! and Thang Obtained in Octo Expansion)
Both sequences can be replayed after being completed by approaching an object and interacting with it to relive memories.
The missions in this sequence are the only ones to feature Fuzzy Ooze, which otherwise only appears outside of missions in The Crater and Alterna.
