Octarians

The Octarians, are a species of octopus creatures who reside in Octo Valley and are responsible for stealing the Zapfish from Inkopolis. Their ink color is a dark shade of magenta.

Description
Octarians usually resemble tentacles rather than full octopuses. They are red and cream colored, with their suckers present on the red side of their bodies, googly yellow eyes, purple lips, and tiny legs in black boots. They come in a variety of forms, and the line is often blurry when it comes to what is an Octarian and what is mechanical, suggesting they may use some manner of biotechnology.
