The Giant Pacific Octopus is an unreleased animal, which can be seen under the skins menu in the deeeep.io beta. It is planned to be released alongside the megamouth shark, beluga whale, sarcastic fringehead, parrotfish, cookie cutter shark, bowhead whale, beaked whale, and Japanese spider crab (If there are any I've forgotten, add them here). It's abilities appear to be a toxic ink cloud larger than that of the octopus which poisons anything in it for 2 seconds repeatedly that only the gpo can see through for charge boost, alongside a 'teleport' where the user goes towards their mouse pointer not colliding with any creatures in their way with the normal boost.
