Breath of the Wild
Oakle's Navel is a location found just west of the Hateno Tower and northeast of Mount Rozudo. It is a geographic depression, with a small lake found at its base. Within the water there is a circle of lilypads that Link can drop into to find a Korok Seed.
In the water below, Link will find some Armored Carp, Mighty Carp, Staminoka Bass, and Hyrule Bass. There are also some Hot-Footed Frogs in the area, as well as an enemy Water Octorok found at the center of the pond. Surround the water, there are several Ore chunks that Link can mine to find Flint, Rock Salt, and various Gems. The area is very steep to climb out of, and there are some Rushrooms on the walls.
