Explore the Cave
Defeat the Bokoblins and Boss Bokoblin that guard the cave. Open the chest to get some Bomb Flowers. Gather ore from the ore deposits.
Next, cut through the vines between the two ore deposits, and at the end of the tunnel you will find some boulders blocking your way. Use bombs or a rock hammer to break these boulders.
One of the tunnels that you can find by breaking the boulders leads north, to Jojon Shrine.
The tunnel that leads southeast goes to a room with a Bubbulfrog.
If you break down the boulders beyond where you found the Bubbulfrog, you will find a Horriblin.
The path that leads east goes to the eastern exit of the cave.
