Upon following the elderly squid Craig Cuttlefish into a crater covered with lethal Fuzzy Ooze, the player is recruited by Cuttlefish into the New Squidbeak Splatoon as Agent 3 along with their pet Salmonid Smallfry known as "Little Buddy" .

They fight Octarian enemies mutated with fur, which Cuttlefish believes are responsible for once again stealing the Great Zapfish that powers Splatsville
