Octolings Ahoy! is the twenty-first stage in the Hero Mode of Splatoon 2 The mission can be found in the fourth sector, Slimeskin Garrison.
The stage takes place in a modified version of Moray Towers at sunset. Octolings allied with DJ Octavio guard eight mini Zapfish, backed up by a pair of Octosnipers, with the Octolings armed with Blasters and Sloshers. They are also reinforced by Sprinklers and Splash Walls. Usually, in other Octoling stages, there are at least one or two Elite Octolings, in this round, there is none.
The Sardinium and Sunken Scroll are located near the Octoling Respawn Point in wooden crates. There are also two Sting Ray canned Specials located on the map, which can be used to help splat the Octosnipers. One is near the Octoling Respawn Point, a second in a corner opposite one of the mini Zapfish in a heavily armored crate.
