Instructions
Fly to Blue Nile Fales on the world map. Jump up to the platforms directly above your landing location.
Once at the top of the waterfall, loot the Egyptian blue lily sitting on the platform. Walk out to the very edge of the cliff side and hold the mouse button in the top right corner to jump out to a ledge in the middle of the waterfall.
From the ledge, jump up the platforms to speak with a woman who will request your aid in getting all of her belongings across the waterfall. Only one item can be brought at a time, and some can not be left on the opposite side alone.
Bring the chicken over in the basket first, followed by the feed. After you drop off the feed, bring the chicken back to the opposite side, drop it, and pick up the fox to take to the side with the feed.
Return to the starting side to pick up the chicken and take it to the side with the fox and feed. Once complete, the woman will tell you where the hidden cave entrance is.
Enter the cave entrance, which is hidden by a bush on the right side of the waterfall.
