Unique Namakos with Special Traits
Shell Namako gathers limestone. Iron Namako is great at mining. Flame Namako and Ice Namako can survive extreme temperatures.

Restore the Ocean’s Beauty
As you decontaminate, corals bloom, sunlight shines through, and the ocean regains vibrant color.
Over 40 types of “Scenic Creatures” will begin to swim in—try to collect them all as you heal the seas!
