All Puzzles Related to Little One
Players must also solve three key puzzles in Natlan to fully unlock the Someday, We All Must Walk Along quest. These activities provide an engaging way to earn progress while interacting with the environment.


The first puzzle involves completing the Urubamba’s Warrior Challenge. Players need to ascend the podium after collecting eight scattered Tatankasaur Whelps around Urubamba’s location, situated northeast of the Statue of the Seven at “Collective of Plent.”


The second puzzle is found near a cliff northeast of the “Flower-Feather Clan.”Here, players must transform into an Iktomisaur to interact with a glowing shape, clearing a rock barrier before proceeding to a platter that requires the ‘Delicious’ version of Saurus Crackers to work.
The final puzzle takes players to the ancient ‘Sea of Shifting Sentience,’ where they should energize the Secret Source Dragon Idol. By using a Tatankasaurus to break through a gate and infusing a device with Phlogiston, players can summon treasures within this mystifying realm.

This hidden domain is the setting for both the initial meeting and the poignant farewell with Little One.
