In Zelda: Echoes of Wisdom, Mogryph is the boss of the Gerudo Sanctum section of the game, and defeating it completes the “A Rift in the Gerudo Desert” main story quest. Beating Mogryph isn’t so difficult when you know how.

Not long after you’ve brought two tributes to the golden door in Gerudo Sanctum, you’ll find the Big Key and use it to unlock an even grander golden door. Don’t go through that door until you’ve got the hard-to-get chest, though. Beyond it is a large, sandy-floored chamber with nothing in it (at first) except one of each of the statues you’ll have seen elsewhere in Gerudo Sanctum: Elephant, Hawk, Cat, and Snake.
