Octopuses are a species in the Animal Crossing series, appearing exclusively as villagers. They are the least common species of villagers in the series, as only four have been featured in the games. They are also the only species with characters not to be in the Chordata phylum. They are easily recognised by their spherical heads, tentacles, and ink-jets which are relocated to mimic mouths. Octopuses are one of the two species that appear as both sentient villagers and also as fish, the other being Frogs.
