Manaphy is a small, blue, aquatic Pokémon. It has stubby feet and club-like arms that are longer than its body. Manaphy has a red gem on its chest, and a yellow dot below the gem. Manaphy has an onion-shaped head with a pair of long blue antennae, which have small spheres on the end. Manaphy's irises are dark blue, although the outermost portions of its eyes are yellow, with two yellow dots of "eyebrow" markings extending from the eyes. Eighty percent of Manaphy's body is made of water and is highly susceptible to its environment. One of these reactions is that when Manaphy reproduces in an ocean that's warmer than those that they are native to, the child will be a Phione as opposed to another Manaphy.
