Dragonzamasu is the second boss of Super Mario Land, and a servant of Tatanga. He is a giant Yurarin Boo.

Dragonzamasu and his servant, the bubble entity Tamao, guarded the end of Muda and entrance to Easton. Mario fought him inside his Marine Pop and destroyed him to access the place where Princess Daisy was supposedly being held, but once again, it turned out to be a common enemy in disguise.

To defeat Dragonzamasu, Mario must either hit him with 20 torpedoes or get under him, destroy the blocks blocking his path, and hit the switch. Dragonzamasu attacks by shooting energy balls at Mario every few seconds, while Tamao flies around trying to hit Mario.
