Lechius

It looks similar to a leech. It lives in lakes of the Antarctic Ground and the Moor and swims through the oceans of the Deserted Island and the Frantic Bay. Lechius has a red body with turquoise stripes on it. Its body is moderately long and has suction cups on the tail. With them the Mollusk can cling onto its target and prick its victim and suck out blood. It has some weird, white excrescences on its body that are in no special order and supposed to be some kind of parasite. It attacks every monster or human in its nearness and sucks health from them. It attacks the biggest living in the water. Lechius is even more persistent than a Giggi but you can easily get it off when you get hit by something. else you need to come on land and "roll" to get it off. The weakness is thunder, then dragon. Lechius are sometimes seen in groups of ten or more individuals attacking a very big monster. They are used in the medicine for certain diseases.
