I've taken my focus away from animating and instead coming up with a Splatoon 4. I have a general idea for the storyline, which will be adjusted based on the final fest outcome.
After being captured during a Salmon Run, a young Salmonling meets Agent 3, who is investigating an old Grizzco base. The Salmonling is dubbed "Agent 9" and teams up with the rest of the Squidbeak Splatoon to escape-and discover who's running Grizzco.
