Hot air fills Flablim's body, lifting it up into the sky. It can expel flammable gasses into the air around it, then ignite them to ascend faster, propel itself against the wind, or fight off any flying Pokémon that attack it.

It's drowzy in daytime, but flies off in the evening in big groups. Flablim's fluffy fur releases heat into the air so that its body does not get excessively hot.
