Giant Squid

The Giant Squid is a large cephalopod that inhabits the waters around the island where Killer B and A trained.

Personality
It serves as a guardian of the island attacking anyone or anything that comes near it, even Kumogakure ninja. He seems to be one of the more hostile animals of the island.

Confining the Jinchūriki Arc
When the Kumogakure ship that was carrying Naruto and his bodyguards, it attacked the ship, but was stopped by Killer B in his Eight-Tailed Giant Ox form. It later attacked Motoi after he came to find Naruto. Yamato and Naruto tried to rescue him but once again Bee was quicker. Some time later the squid encounters Manda II, and was torn to shreds after getting in the giant snake's way.
