The Miros Underground
Gelatinous cubes scour dungeon passages in silent, predictable patterns, leaving perfectly clean paths in their wake. They consume living tissue while leaving bones and other materials undissolved.
A gelatinous cube is all but transparent, making it hard to spot until it attacks. A cube that is well fed can be easier to spot, since its victims’ bones, coins, and other 9bjects can be seen suspended inside the creature.
