The Volcano's Base

The Volcano's Base is the second level on the west side of the music box world in Wario Land 3. After obtaining the two halves of the scroll from both the Desert Ruins' Gray Chest and Red Chest, the storm is calmed, then this level becomes accessible.

The level is set at the base of the volcano located in the center of the music box world. Besides the usual enemies like Spearheads, the level features many slopes on which Wario can perform his rolling attack. There are also some caves to be found and also a big, flooded cavern located underneath the level. In the higher area of level, there is a set of rails with carts on them.

Gray Chest: Lead Overalls
The Lead Overalls, also known as the Jump Smash Overalls , is in the Gray Chest, which can be obtained after defeating the level's boss, Doll Boy. It is accessible from the start.

The Gray Key to open this chest can be accessed by rolling from the second slope to the right from the beginning. From there, Wario must jump to break through the set of blocks along the narrow passageway towards the Gray Key.

In order to access the room where Doll Boy is, Wario must roll from the same slope to break the blocks to the left of the Warp Pipe. Instead of going towards the narrow passageway, Wario must jump to the thin platform in between the two narrow gaps to jump over the hill, and then go downwards to reach the pipe. Should he miss it, there is a slope to the left of the pipe to roll back towards the same slope.

After entering the Warp Pipe, the boss battle immediately starts. In battle, the Doll Boy attacks by throwing hammers at Wario, which triggers Bouncy Wario upon contact and ejects him out of the arena. In order to be able to damage the boss, a Dash Attack is required to knock off the barrels as they flash. After the three barrels are knocked away, the boss will pursue Wario by swinging its hammer. Attacking the boss from any side except for the front while it swings its hammer will leave it temporarily vulnerable, where a Dash Attack will defeat it. After defeat, a floating hammer will appear that will lead directly to a door. Behind the door, Wario will drop to where the Gray Chest is.

The Jump Smash Overalls allows Wario to use a Smash Attack, allowing him to use a Smash Attack which can smash through cracked blocks, defeat enemies, and move certain creatures out of the way from above. This opens the way for new treasures in Out of the Woods and The Vast Plain.

Red Chest: Blue Gem
The Blue Gem, also known as the Blue Relic , is in the Red Chest. To access it, the Wheels from The Grasslands's Red Chest is needed, as they will repair the carts through fitting the wheels on them, and thus become operational.

In order to get to the area where the Red Chest is, Wario must roll from the first slope near the beginning to reach the door along the lower floor. In this room, there are five Nobiiru along the ladder and a Para-Goom atop the ladder. The Warp Pipe is in the ceiling, which leads to the upper portion of the mountain where the carts are. The cart near the beginning will move from left to right towards the Red Chest, but along the way are obstacles such as Spikes and Fire Robota and platforms that needed to be crossed or jumped over. Next to the Red Chest is a ladder, which has another cart all the way down from it. This cart moves from right to left, where there are also obstacles along the way. The Red Key is past the first set of platforms, reachable by crouching past the narrow gap.

After obtaining the Red Key, the cart can be ridden all the way to the left where a ladder is, allowing Wario to return to the first cart. If Wario falls from any point, he must re-enter the door to go back to the upper portion of the mountain to get back on the cart. The Red Chest is at end of this rail.

The Blue Gem does not affect the world in any way.

Green Chest: Crown
The Crown is in the Green Chest. It can be accessed after obtaining the Flute from The Stagnant Swamp's Gray Chest, which summons the snakes from the pots.

Like the Red Chest, the Key and Treasure are found in the upper portion of the mountain. The first cart must be ridden until Wario reaches the platform with a door and the snake pot. The Green Key is located within the room next to the pot, where it is found by going underwater, then going down and right, and the up to the air where the key is.

The chest is accessible after jumping from the snake's head from the highest point, but the path is blocked by a mini-game block to the right. The Golf minigame to open the entrance is to the left across platforms past the Fire Robota. After completing the minigame, the block opens up the path to two platforms before the entrance to the Green Chest, which is down the ladder.

The Crown does not affect the world in any way.

Blue Chest: Tusk (blue)
The Tusk in the Blue Chest. It is accessible after obtaining the Foot of Stone in The Tidal Coast's Red Chest, which creates an earthquake strong enough to cause a collapse on the left side of the level and opening up access to the left and the pit below.

From the beginning, the room to the Blue Chest is to the left. There is also a slope which can be used to roll down into a flooded cavern below the ground. To access the Blue Key, Wario must swim four levels below to reach a set of breakable blocks to the left, which must be broken from below before riding a bubble as Bubble Wario past the current.

To escape from the pit, Wario must go to the door at the floor of the cavern. Within the door, there are a few Spearheads and a set of Kobatto that triggers Vampire Wario. In order to fly out of the cavern, the blocks along the way must be destroyed first. After that, Vampire Wario must fly as a bat to the topmost part while avoiding water droplets. The Warp Pipe leads to the ground above, where going all the way to the left and then up towards the leftmost door leads toward the Blue Chest inside the room.

The blue Tusk, along with both the red Tusk in The Steep Canyon's Red Chest and the Green Flower in The Stagnant Swamp's Red Chest, causes both The Colossal Hole and The West Crater to become accessible as a result of the volcano's eruption due to the gathering of the three treasures.
