"The Wind Slime finds it hilarious to sneak up behind you and blow in your ear. Actually, its a combination of blowing and spitting."
— In-game description

Wind Slimes are a species of amorphous, non-sapient blobforms which inhabit the windy regions of their home realm. Like other slimes, they have small, beady eyes and a concave area used as a mouth. Wind Slimes are capable of casting the Lightning spell. They are likely the prey items to the Giant Worm, which can be considered the local apex predators in the Cliffside and Mountain Pass regions; it can be assumed the Giant Worms eat all inhabitants of these biomes indiscriminately.

As they would need to consume sustenance to stay alive but they are relatively small, it is assumed the smallest creatures known to exist in each of their biomes would be their most likely prey items. They appear to consist at least upon slugs, although it is assumed this would not be enough to sustain an organism of this creature's size. If this is so, than that would mean that they must supplement their diet by also consuming Bolts found in all four regions, the Whips in the Cliffside and Mountain Pass areas.

Wind Slimes have adapted to survive in incredibly windy environments, presumably thickening their gel-like insides to prevent their being whipped around constantly. This costs them their invulnerability to earthquakes though, and they have become weak to it instead. They also likely consist of an alcoholic content that provides excellent static charge for their lightning attacks.

Like the Earth Slime, their original habitat range has been divided and they are now divided between a population found around the Light Tower near Crystalia and a much larger group found in the Highlands, Cliffsides, and Mountain Pass.
