Yurarin

Yurarins are enemies that appear in Super Mario Land. Yurarins are seahorse-dragon enemies that can only be found in World 2-3 of the Muda Kingdom. Their leader is Dragonzamasu.

History
Yurarins are found in the underwater level of the game and the only thing they do is float slowly in the water. Mario can very easily just swim by them or shoot them down with his Marine Pop. Stronger versions of Yurarins known as Yurarin Boos also appear in the same level where they shoot fireballs to attack.
