Biokinton is a cloud creature. He is the fourth boss of Super Mario Land, and servant of Tatanga. Unlike the previous three bosses he does not resemble any previous enemies, but behind the cloud is a shy creature no one has seen.
Biokinton guarded the end of Chai Kingdom. Mario reached him in his Sky Pop and defeated him. Immediately after he was destroyed, Tatanga appeared in a final attempt to destroy Mario himself, but was also defeated.
Biokinton flies around the screen and shoots Chickens at Mario. Mario can destroy these with torpedoes. To defeat Biokinton, Mario must shoot twenty torpedoes at him. There is no switch to automatically destroy him.
