Welcome to the theory board. Canon, for our purposes, is: the three games, the Octo Expansion and Side Order DLC, the Sunken Scrolls, the Alterna Logs, in-game dialogue and Splatfest results, plus the official artbooks and the Squid Research Lab posts. The manga and Splatoon-adjacent Smash trophies are fun but secondary.

When you post a theory, quote the scroll or log you are building from. The best threads here start from something a character actually said.
