The Pool of Rain

The Pool of Rain is the third level on the west side of the Music Box World in Wario Land 3. Wario unlocks both this level and A Town in Chaos after finding the Jar in Out of the Woods, which causes a rain cloud to pop out and filly the empty pool blocking his path.

Gray Chest: First Gear for Machine
The First Gear for Machine can be found in the Gray Chest among several small brown platforms over the pool. Ground Pounding one platform will make it sink and cause another one to rise, and the player must navigate these platforms to reach the area where the Gray Chest and its key are located. Opening the treasure chest rewards Wario with the First Gear; when paired with the Second Gear, found in A Town in Chaos, the elevator machine in the east side becomes operational, opening the path to The Grasslands.

Red Chest: Skull Ring
The Skull Ring in the Red Chest requires the Magic Seeds from The Big Bridge, which causes a vine to grow in The Pool of Rain; this allows Wario to access a new area where the Red Key is found. A door near the entrance to the level contains the Red Chest, and unlocking it reveals the blue Skull Ring. When paired with the red one found in The Vast Plain, the Tower of Revival will emerge from the ground in the south side.

Green Chest: Ornamental Fan
The Ornamental Fan in the Green Chest requires the Swimming Flippers from the Tower of Revival to swim through a watery area containing a Haridama surrounded by spikes. Beyond the area, a door leads into a large room with several aquatic currents that will push Wario in various directions; Wario must navigate them to reach the Green Key and the level's boss, Wolfenboss.

Wolfenboss attacks by shooting energy balls at Wario, which he must dodge until Wolfenboss throws a spiked ball at him; the spiked ball will open and produce a Chestnut if Wario avoids it successfully. Wario must attack the Chestnut at the right angle to bounce it off the wall behind Wolfenboss and hit him. Three hits will defeat Wolfenboss and open the path to the Green Chest, which contains the Ornamental Fan. The fan is needed to open the path to The Stagnant Swamp by blowing away a cloud of mist in the south.

Blue Chest: Crayon
The Crayon in the Blue Chest requires the Air-Pump from The Colossal Hole, which affects the room to the right of the spike area, allowing him to reach the door underwater. The door leads to a cave full of Pneumos, with the Blue Key to the right of the cave. The Blue Chest is on the left side of the cave in an area that Wario can only reach by using a Pneumo to turn into Puffy Wario, and opening it rewards Wario with the crayon.

Once collected, the crayon flies to a hill on the north side of the world, where a tower with a sign reading "GAME" resigns; the yellow crayon colors in the sign. Once Wario finds all seven crayons hidden throughout the game and gains access the tower, the player can then play the golf mini-game at any time.
