Official Description
A formidable aquatic serpent that crests on moonlit nights—likely why it has often been mistaken for a mermaid.

    • I saw that Magnamalo has two names: some shoos are selling Magnamalo Amiibo and some shops and selling Magbanaki Amiibo but they’re both the same monster. Why is that?

    • I hope they have different accessories for the Palamute like how the Palico can use Palico Gadgets! Maybe fang accessories which could inflict Poison, etc.?
