Drifloon has a round, purple body with two stringy arms that have a yellow heart-shape on the end of them. Drifloon has black, dotlike eyes and a yellow "X" on its face; as Drifloon may be interpreted as the ghosts of popped balloons, this "X" may represent two pieces of tape intended to cover the hole that would have caused the balloon to deflate. A white mass of fluff that looks like a cloud sits on top of Drifloon's head.
Gender differences
None.
Special abilities
Behavior
Drifloon usually try to grab children in attempts to bring them to the underworld, but these attempts always end up with the Drifloon getting swung around. Being filled with air lets Drifloon either expand or shrink to express its feelings.
Habitat
Drifloon drifts into (and presumably lives around) the area of Valley Windworks, and prefers damp weather.
"A Balloon Pokémon that appears each Friday at the Valley Windworks in the Sinnoh region. It's round and cute, but it has a dreadful side too, as it attempts to drag children into the underworld by their hands. It likes damp, humid seasons. If it's on the verge of fainting in battle, it will counterattack by self-destructing. It evolves into Drifblim."
Game data
Pokédex entries
This Pokémon was unavailable prior to Generation IV.
In the Japanese version of Pearl's Pokédex entry, Drifloon specifically take children to the "world of the dead" (Japanese: あのよ), instead of just trying to "steal them away" as in the English version. However, in the US release of Super Smash Bros. Brawl, the description along with Drifloon's trophy still states that it is "taking children to the underworld".
Drifloon shares the same species name with Jigglypuff's evolutionary family and Qwilfish. They are all known as Balloon Pokémon.
However Drifloon is the only one of them that actually resembles a real-world balloon.
Drifloon is one of six Pokémon that has type-based immunities to three different types, the other five being Drifblim, Sableye, Spiritomb, Golett and Golurk. All six of them are part Ghost type.
