Notable members

Yurarin Boo[1][2] are fire-breathing seahorse enemies found in Muda Kingdom in Super Mario Land. Unlike their little brothers, 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.

In the Game Boy comic books spun off from the Nintendo Comics System, produced by the company Valiant, Yurarin Boos made cameos where they could fly, and be used as mounts by Pionpi.

In the Super Mario Land manga, a large Yurarin Boo is encountered in the Muda Kingdom, blocking Mario's way, who is unable to damage him with Superballs. It is rendered helpless after its mouth is tied shut and his fins are bound, and Mario and Mekakuribō keep it with them as a hostage that can guide them to the area boss. The Yurarin Boo is unwillingly cooperative and snarky at times, but does help during the boss battle: after Tamao cracks the Marine Pop's glass, Mario and Mekakuribō use the Yurarin Boo to stop the leak. After Tamao tries to hit them again, the Yurarin Boo grabs it, allowing Mario to shoot Dragonzamasu. After Mario and Mekakuribo leave Muda Kingdom, the Yurarin Boo decides to quit being a minion and opens a takoyaki shop.

Yurarin's fire-breathing brother
He is Yurarin's older brother, leaping energetically out of the sea and breathing fire. Since the superball does not work, you have to stomp on him, but you can defeat Yurarin Boo in the sea by hitting him with a torpedo.
