"Cold Slime is happy to keep things frozen for you... and you. Much stronger than his Crystal Story counterpart, by the way."
Cold Slimes are a species of amorphous, non-sapient blobforms which roam the cold 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. Cold Slimes are known to mature over time, becoming more powerful as time goes on.
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 regularly consume Frost Bats in the Icy Pass; Frost Spiderlings in the Frost Fort (although Frost Widows are likely too large and large a threat to take on); and Ice Goblins in the Frost Fort, Harpy Forest, and the Snow.
Being presumably primarily alcohol based like the Glooples and presumably all other blobforms, they are highly susceptible to combustion and adventurers can use this to their advantage; immolating a Cold Slime will deal twice as much damage to them as would otherwise have occurred. They also are invulnerable to earth-based attacks, likely jiggling around like gelatin and as a defense against earthquakes.
Interestingly, they are not found in either the Icy Cave or Icy Forest, which separates the Snow and Icy Pass from the Frost Fort and Harpy Forest. This may mean that they are slowly being wiped out, though if they can survive such an event these two populations will likely divide into two subspecies over the next few thousand years - assuming that they do not repopulate the areas they have presumably disappeared from.
