Yurarin Boo

Yurarin Boos are fire breathing seahorse-like dragons found in Muda Kingdom in Super Mario Land. Unlike their slightly smaller cousins, the Yurarins, Yurarin Boos can move up and down shooting fireballs. On some occasions, Yurarin Boos 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 Boos are more common than Yurarins, even though they are stronger. They appear in all three levels of Muda Kingdom. They are under the assumed leadership of Dragonzamasu, who is possibly an even larger version of a Yurarin Boo.

Trivia

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