"The Fire Slime is almost the same as the Earth Slime, except it tries to barbecue you. It also has a (slightly) higher chance to kill you."
— In-game description

Fire Slimes are a species of amorphous, non-sapient blobforms which inhabit the Orange Pass, along the border between the forested and desert regions of their home realm. Like other slimes, they have small, beady eyes and a concave area used as a mouth. Fire Slimes are capable of casting the Fire I spell.

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 local Scorpions species.

Despite being presumably primarily alcohol based like the Glooples and presumably all other blobforms, they have adapted to their genus' heavy susceptibility to combustion; however like all other evolutions, this adaptation does not come without its cons: They have instead become weak to water, which likely cools them off too fast for them to deal with, possibly bursting their skin in the process and causing them to leak everywhere. They have also lost their invulnerability to earth damage, perhaps indicating that their alcoholic insides are more gelatinous than that of their close relatives, the Earth Slime.
