Drifloon is a Pokémon that has a spherical, purple body with two stringy arms that have yellow, heart-shaped hands on the ends of them. At the base of its body is a frayed protrusion that resembles the tied end of a balloon. In the very center of its body is a yellow tape-like "X", which contains its small mouth in the very center. Located on either side of the "X" are its small, black eyes. A white mass of fluff that resembles a cloud sits on top of Drifloon's head.
This Pokémon is known as a "Signpost for Wandering Spirits" due to its aimless drifting. Drifloon seeks out children due to it desiring company and it has been known to steal those that mistake it for a regular balloon. However, it dislikes stealing heavy children. They are created from many souls gathering together and it's round body continues to expand as it collects more. When the body explodes, the soul unleashes a screeching sound. However, due to its light weight, it can be resisted easily and is often pulled around. This results in Drifloon running away from any children that are rough with it. Although created by the lost spirits of Pokémon and people, as seen in the anime, it can be friendly and helpful. It prefers to reside in damp, humid locations and can expand or shrink to express its feelings.
