Tako

An Octo is a small orange octopus, similar to the squid-like Blooper. They have only appeared in the game Yoshi's Safari. During the events of the game, Octos aid Bowser and his Koopalings during the subjugation of Jewelry Land.

Mario and Yoshi encounter Octos in the fourth level of the Light World, Crescent Coast. While traveling underwater, they have to fight off an assault from these weak creatures. The Octopot, a giant jar-like creature, launches wave after wave of Octos at Mario and Yoshi. Fortunately, the small cephalopods can easily be destroyed with a couple blasts from the Super Scope. After shattering the Octopot, the Octos disappear, never to be seen again.

An Squid-like thing named Octo appears in Dr. Mario 64 as a character disturbed by Dr. Mario/Wario. He often suffers from headaches and is cured by Megavitamins. He has the body of a squid, but has the face of a cat.
