Bring 2 Un'Goro Gorilla Pelts, 2 Un'Goro Stomper Pelts, and 2 Un'Goro Thunderer Pelts to Torwa Pathfinder at the entrance of Un'Goro Crater.
This crater has many strange creatures--they seem to be nobler versions of the creatures found throughout my homeland and beyond. I cannot explain it, but this place cries of the Earth Mother. I pay homage to her every time I track one of her beautiful creatures across its basin.
If you too wish to feel the enlightenment that accompanies such a great feat, then head to the north. There you'll find great apes who are a test for any mortal's strength. Bring me their pelts... prove your strength.
