Yurarin Boo

Yurarin Boo are fire breathing seahorse-like dragons found in Muda Kingdom in Super Mario Land. Unlike their slightly smaller cousins, the Yurarin, Yurarin Boos can move up and down shooting fireballs. On some occasions, Yurarin Boo can also be found outside of the water. They are also known to be invincible to superballs. To defeat one, Mario has to stomp one's head or shoot it with two of the Marine Pop's torpedoes. Defeating one awarded Mario with 400 points. Yurarin Boo are more common than Yurarin, even though they are stronger. They appear in all three levels of Muda Kingdom. Dragonzamasu, the boss of the Muda Kingdom, resembles these creatures.

Trivia

 * Despite the name, the Yurarin Boo is not related to the Boo species. Instead, it comes from the Japanese name, Yurarin Pū.
