Rivmoril

A rivmoril is a beast that eats meat. It has a mole like body. On the back is a big sack with gas. The head has two eyes and and mouth from which two fangs can pierce into enemys. From under its head it can extend a triangular spike. If it hits its fangs on this spike it makes a spark which can light the gas. To get the food it sets traps. For that it digs with its frontal paws a small hole that its gas sack fits in. To detect if an animal runs past it uses its ears, which can hear the thud of the feet on the ground. It waits for the right moment and then shoots the gas onto the enemy. This gas irritates the animal and gives the {rivmoril} enough time to light the gas with its fangs. After the trap worked it changes the location to get out of the now stinking area. The combustion stinks like brimstone and sulfur.
