Located in the Lost Ark universe, Naruni Island is home to the adorable and somewhat prehistoric-looking Narunis. There isn't much to accomplish here besides acquiring Island Souls and gathering all five Mokoko Seeds.
You need not return to Naruni Island once you have obtained the Island Soul and all the Mokoko Seeds because there is no Una's Task connected to the island. There is no real reason to return unless you want to kick back with some Narunis.
The location of Naruni Island.
It is in the Sea of Procyon, past the central Wall of Procyon, that you will find Naruni Island. It's not far from the harbor of South Vern (Bellion Ruins).
Having an Attitude of an Islander
Even while acquiring the Island Soul for Naruni Island only requires a single quest to be finished, you shouldn't underestimate its difficulty. Even though this is a welcome change from claiming tokens based on random chance to get lost ark gold cheap, the process still takes some time.
The Environmental Researcher can be found near the island's entrance, and the mission (Naruni Go!) needs you to interact with the Narunis there a total of 101 times (a clear reference to 101 Dalmatians).
This may appear simple, but these critters are constantly on the move. It's important to pace your interactions with them so they don't run away from you while you're still interacting with them for quest credit, which can take a few seconds.
Number One Mokoko Seed
When searching for the first Mokoko Seed, you will have a difficult time finding it (the only way it becomes visible is if you zoom in as far as you can while standing right next to it).
You can access the Mokoko Seed from a secret gate in the island's north (shown above), and the game will advise you to do so long before you ever come into contact with it.
Two and Three Mokoko Seeds
Mokoko Seeds Nos. 2 and 3 are missing from the map. There is no bouncing yellowish-gold arrow at this wall, but the game will offer you the chance to climb it if you get close enough to it in the center of the southern strip of the island, as indicated in the left image above.
Both seeds are located at the top of the second wall you must climb after reaching the first (right image).
This is the Fourth Mokoko Seed
The fourth Mokoko Seed can be found in the island's fertile east, where there is the most room to roam. It's concealed in a bush of reddish-purple blossoms beneath the canopy of a tree.
Fifteenth Generation Mokoko Seed
The fifth and final Mokoko Seed is located a little distance north of the fourth seed on the same side of the island. A tree is casting its shadow on it, and the nearby bushes make it hard to see, so be vigilant.
