Splatoon 3 DLC Theories! Is that Marina?

Well it took a couple days, but I FINALLY finished this video! It is time for some theorizing based on the trailer we got for the upcoming Splatoon 3 DLC that we got during the Nintendo Direct. I am so hyped for this, and hope you like the theories. Let me know in the comments what you think could be going on in this trailer.

Clip from @ArloStuff's Direct Reaction comes from here:
