Octillery are red cephalopod Pokémon with turret-like mouths, yellow bumps on their rock-hard heads, and yellow suction cups on each tentacle. They possess eight tentacles, two of which are used for manipulating objects while the other six don't appear to be used as much aside from a stabilizing role.
Female Octillery have smaller suction cups on their tentacles. The yellow bumps on their head are also smaller.
Octillery are relaxed Pokémon who love fuss from their Trainers. Wild Octillery will spurt ink at predators to protect their young from danger. Even though caught Octillery are more docile, wild Octillery can be very stubborn at times. Octillery instinctively sneak into rocky holes, and if it gets sleepy, it steals the nest of a fellow Octillery. It sometimes sprays ink on prey by sticking out only its mouth, and its suction cups hold prey tightly.
Both Octillery and Remoraid are normally found in oceans. However, they are occasionally found in freshwater lakes.
