Giant, mutant mollusks that can be encountered in From Software's 1995/1996 King's Field Sony Playstation first-person RPG (roleplaying game). It should be noted that said title is actually King's Field II, but, as the first game wasn't released in North America or Europe, the publisher decided to start the numbering system anew for those regions (likewise, King's Field III was retitled as King's Field II in said markets).

This omnivorous gastropod is always hungry and has two options for bringing down its prey. If the target is close enough, the left head will simply lunge forward to take a bite out of its victim. On the other hand, if the potential meal stays outside of the mollusk's reach (and that's frequently the case, as the S-Knight moves very slowly), the right head will exhale a plume of acidic mist in their general direction, which, in addition to inflicting injury, will also poison the victim if it makes contact. It doesn't matter if this caustic vapor kills the target outright or not, because the toxin coursing through their system will shortly finish the job--all the S-Knight has to do is follow the trail left by its ailing victim until they inevitably succumb to the poison and collapse. While both of a S-Knight's attacks are relatively easy for an adventurer to avoid if they can stay near the sides, or rear, of the shell, where the creature can't easily see or reach them, particular care must be taken when confronting multiple monsters at once, as it's all too easy to get outflanked and sprayed by one S-Knight while you're trying to deal with another.

As one would expect, striking a S-Knight's shell is an exercise in futility, as this natural armor is incredibly hard and durable, making it completely impervious to conventional weaponry. The creature's relatively soft heads and necks are what an adventurer should try to target when attempting to deal damage to this slimy adversary. S-Knights could hide inside their shells, for additional protection, if necessary, however, due to their large size and aggressiveness, very little intimidates them (armored humans brandishing weapons and spells don't impress a S-Knight in the least), as such, it's almost unheard of for one of these monsters to take a defensive stance when threatened. Slain S-Knights occasionally drop crystal shards but never gold pieces (snails have no interest or need for money, but apparently the slimes, fish, and man-eating plants in King's Field do--figure that one out).
