Foamers. Marine beings form the Cantabric, northern Spain coast. Their appearance is that of fat children. They wear tunics that are the color of algae. They like to play in top of the waves, forming small whirlpools in them. The Sirens are their friends, and they usually give the Espumeros seashell trumpets as a gift. As those marine beings are very good, willing and helpful to fishermen, they blow into their sea trumpets when there is going to be a storm. Thus the seamen are warned that it is safer to return to port. Espumeros also help farmers sometimes, carrying water in their trumpets to water the crops.
