Are you wondering where to go next after finding the Wind Idol and Holy Orb? Give the Idol Research Lab a visit. The researcher there will tell you where to look for the Thunder Idol.

There is another researcher inside. He is a scout for the Dwarf that stamps your stamp card and he needs your help researching three things that have sunk in the ocean. One of them is the Water Temple which you have already found, so you only need two more.

On this island, there is the Cave of Darkness 2 and Fishing Spot 5. By using the warp zone at Fishing Spot 5, you can travel to the Cave of Darkness 3. We'll talk about the Cave of Darkness 2 and 3 next time.
