The snails produced an incredibly sticky slime, as well as an oily grease that neutralised the effects of the slime. The trogs could force a snail to eject this oil by pulling one of its feelers. They varied greatly in size; the largest ones being the size of a bull hammelhorn, and the smallest being able to fit in the palm of your hand.
The slime-snail oil was flammable, and could be used as fuel. The trogs used upturned snail shells filled with burning oil similarly to braziers, as a source of light in their caverns.
Small shells could be used as musical instruments, such as snail-shell horns, producing a low, booming, sonorous sound, or they could be punctured to make flute-like noises when the wind blows through them.
The slime the snails secreted was used as a glue, and coated cave-spider silk to create strong, yet flexible ropes.
While spidersilk was used for the high-quality robes of the Trog Queen and the highest-ranking females, snailskin clothes were worn by most trogs, and it was also used in capes and curtains.
