Origins

The US localization changed his name to and instead, he is the ruler of the dream realm. In Link's Awakening he retains his original Japanese name, Mamu, in the English localization.

Theory
After being defeated at the hands of the hero,, the real and the  had the evil frog king caught. However, 's backstory reveals that he fled to another dream world before returning to Subcon, possibly being the Wind Fish's Koholint Island. This might support the fact that Mamu vanished in Link's Awakening after teaching Link the Frog's Song of Soul.

There is another theory that Mamu is still an enemy despite how friendly he acts in Link's Awakekning, as his conquest of Subcon is not necessarily over. There are still members of his army, the, who inhabit Koholint Island, such as Bombites, Mask-Mimics and Pokeys. There could be some possibility that he may still command the 8 bits (probably also the members of the Koopa King's army) while acting like an ally.

There's a possibility that Mamu may have awakened from his endless slumber after the Wind Fish awakened, due to the fact that he can only appear in a dream world by sleeping.
