Essentially a gelatinous cube equipped with 1d12 pseudopods for locomotion (movement rate equivalent to a human) and lassoing prey. Particularly useful in dungeon environments. Followers of Grugzaret use them as enforcers and assassins -- they are absolutely silent and invisible in darkness.
Some gelatinous golems (10%) are equipped with green slime cavities. These are connected via duct to each of the golem's pseudopods. By contracting its gelatin, the golem can spray green slime up to 30 feet away with considerable accuracy.
