First Visit
Right after buying Jewel of Open, you can access this area early.
 * (37,21):The first thing is to snatch a Zircon from the pot in front. Drop down the shaft with a few Spear Guards, now taking advantage of the platforms.  The first exit to the right leads to a save room, the second cannot be accessed without Soul of Bat, and below is a pit leading to the room below.  The left exit leads to another shaft where you can climb up from the bottom.
 * (36,22) to (36,31):Other than Spear Guards, you will also face Bone Archers in the shaft. Take in mind that Spear Guards can utilize their extendable spears.  Note the exit on the left at (36,29), and the Toadstool at (36,31).
 * (34,22):You can find a Heart Container, but this room has a secret on the left wall, with a Bandanna in the room behind.
 * (35,29):Move up to find a Life Vial in another room. For those playing Sega Saturn version, there will be a door on the left, leading to.
 * (37,32):To the right is another save room. At the bottom of the room, move to the right to encounter a boss, and you may want to break the floor to discover a hidden area, only finding it a watery-end.  Instead, proceed to the left.

Second Visit
Assume that you have obtained Leap Stone for more mobility, and Merman Statue to unlock a new area.
