Industrial Squee-G
From Inkipedia, the Splatoon wiki
Industrial Squee-Gs are enemies in Splatoon 2
Unlike normal Squee-G these machines travel on the ground. Industrial Squee-gs will suck up any ink the player has left behind. They ignore Octarian ink, but will instantly splat Octarians if it runs over them. Industrial Squee-gs are large enough to be inked, and if an Inkling gets on top of it they can guide its movements by spraying paths of ink. Unlike the standard Squee-G, Industrial Squee-Gs will also chase Inklings and will splat them on contact.
