Death Road

It wasn't known much from the Death Road monster until an adventuring group defeated an adult specimen. Most of the information here is coming from them.

The Death Road is an ambush predator. It can dig itself into any soil and waits for its prey. It can also burrow a tunnel for itself, so it is not uncommon that there isn't any sign of digging on the surface. Its body is roughly 20-30 feets in diameter. It has ten tentacles that can grab its prey and move to its vast center mouth. Because of its size, the Death Road monster can swallow whole more than one unfortunate victim, and its stomach is poisonous. Its color is greyish brown. Even exposed, it is hard to distinguish from regular dirt.

There are two features of this aberration that makes it even more terrifying. One is that it has two extremely long and thin tentacles. The length of these tentacles can reach 100 yards, but they are only one inch thick. The Death Road burrows these tentacles as far as possible and excretes a special fluid that can make the soil loose to grow a unique fungus. This fungus is delicious, and its hallucinogenic ingredient makes herbivores easy prey for the Death Road. It can also be a death trap for curious individuals because these fungi grow parallel, along the tentacles like two edges of a road. First, the color of the fungi is yellow, but as you get closer to the monster, the color becomes ever darker and completely black next to the Death Road. The adventuring party mentioned above found the Death Road this way.

Its second feature is that it can grow additional tentacles. When one tentacle is destroyed, it can grow two more instead of the destroyed one. Luckily, fire can hinder the growth of extra tentacles, but the body of the Death Road must be burned continuously until the monster dies.
