Twintacle Octotrooper
From Inkipedia, the Splatoon wiki
Twintacle Octotroopers are a variety of the Octotrooper in Hero Mode. Unlike regular octotroopers, their body consists of two tentacles, and fire rapid-fire bursts of ink at the player when spotted. In addition, Twintacle Octotroopers use their second tentacle to move around their vehicle, which can be trapped in the player's ink. They also have a shielded variant.
