Octoseeker

Octoseekers are Octarians in Splatoon 2 and the Octo Expansion.

Description
The Octoseeker is a helicopter made by the Octarians for reconnaissance and attack. It is piloted by a (presumably elite) Twintacle Octotrooper, which uses a joystick to move the craft and a button to raise and lower it. The front contains a window for the Twintacle to see out, which is uninkable. The back contains a door and an A/C unit, presumably to keep the pilot comfortable.

Behavior
They are flying enemies and patrol around an area, raining down ink. If they spot the player, they try to fly directly above them before falling down to crush them. They then stay on the ground for a while, letting the player climb up on top of them. They look and behave similarly to an Octostomp.

Prima Guide Description
The Octoseeker is essentially a helicopter piloted by an Octotrooper. (sic) This aerial vehicle is equipped with a searchlight that constantly scans the ground for threats. If you’re detected, the Octoseeker will hover overhead before eventually slamming into the ground. When the searchlight turns red, that’s your cue to move out of the way—if you stay put, you’ll be squished. When the Octoseeker hits the ground, immediately ink one of its sides and swim to the top to take a ride. You can’t ink the front of the Octoseeker, as the cockpit window is not an inkable surface. Once on board, ink the top of the Octoseeker and look for opportunities to squid-jump to nearby platforms along the vehicle’s patrol circuit. When jumping off, be mindful of the four rotors on the corners. Hitting one of these may interrupt your jump, causing you to fall short of your intended landing spot.

Trivia

 * The bottom of the Octoseeker looks exactly like the Octostomp's face.
 * Like Octostamps, Octostamp DXs, and the Octostomp, the stamp leaves an imprint on the ground.
 * The Octoseeker is the rarest non-boss enemy in, with just seven instances overall - six in Octo Canyon and just one in the Octo Expansion.
