The Volcano's Base

The Volcano's Base is a location found in Wario Land 3 of the Wario Land series. It serves as the second of six levels found on the west side of the music box world. When Wario first arrives at the west side in search of the five music boxes, he finds the path to The Volcano's Base blocked by a raging cyclone. After obtaining the two halves of the scroll from the Desert Ruins' Gray Chest and Red Chest, the storm is calmed, then the level becomes accessible.

The level itself 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. Reachable from the main area, there is also a set of old and inactive railroads somewhere above the level.

Gray Chest: Lead Overalls
The Lead Overalls, also known as the Jump Smash Overalls , is in the Gray Chest guarded by an animated called Doll Boy. The Gray Key to open this chest can be accessed by rolling from the second slope to the right from the beginning. The blocks to break through are the sets of breakable 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 forces him out of the arena. In order to damage the boss, a Dash Attack is required to knock off the barrels as they flash. After all three barrels are knocked away, the boss will pursue Wario by swinging its hammers. Attacking the boss from its vulnerable point, particularly from the top will leave it vulnerable, where attacing with 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 are a pair of blue-colored working pants that allows Wario to use a basic Ground Pound attack, allowing him to use a Smash Attack which can smash through cracked blocks, defeat enemies and move certain creatures out of the way. 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 hidden inside the Red Chest near the inactive railroad system above the level. The carts needed to complete this challenge can be accessed right from the start, but in order to make use of them, Wario first needs to find the Wheels from The Grasslands's Red Chest to allow them to move.

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, and can only be accessed after obtaining the Flute from the Gray Chest in The Stagnant Swamp, 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 is initially blocked by thick solid rock. It is inaccessible until obtaining the Foot of Stone in The Tidal Coast's Red Chest, which creates an earthquake strong enough to cause a collapse around that part.

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 first, and then ride 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 is a set of Kobatto that triggers Vampire Wario. In order to fly out of the cavern, the blocks along the way must be smashed first. After that, Vampire Wario must fly as a bat to the topmost part while avoiding water droplets. The pipe leads to the ground above, and by going all the way to the left and the up towards the leftmost door, the Blue Chest is found.

The Tusk is part of a set of three mystical items. The other Tusk and the Green Flower are found in The Steep Canyon's Red Chest and The Stagnant Swamp's Red Chest, respectively. When brought together, these items cause the volcano to erupt and open the path to The Colossal Hole and The West Crater.
