Beneath the Waves

Beneath the Waves is the fifth level on the western side of the music box world in Wario Land 3. Wario can reach this level once he finds the Red Music Box in The Stagnant Swamp's Green Chest, causing a whirlpool on the surface to form after its music is played.

The level is located deep under the western sea, thus it is set mostly underwater. In the middle of the level, there is a current moving in a loop that resembles a whirlpool, and within the middle, there is a cave in which every chest is accessible from here. Besides the main area, the bottom area also contains a series of currents, and the left area contains a current moving towards the right. The area to the right does not contain any currents, where it is instead a cave that is mostly land.

Gray Chest: Explosive Plunger Box
The Explosive Plunger Box is inside the Gray Chest. It is available as soon as the level is unlocked.

The Gray Key is within the cave above the surface to the right. Within this cave, there are multiple columns with thin platforms, which requires using the Spearhead to bring to the right to bounce off it. Above the platforms, there is a Fire Robota. The Gray Key is above the sixth column of thin platforms.

The Gray Chest is located in cave in the middle of the current moving in a loop. In order to get there without the Prince Frog's Glove, Wario must go to the current from the right, where there is a current moving to the left, allowing him to move downwards to the entrance. Within the cave, in addition to multiple ziplines, there are two Spearhead, a Beam Robota, and a Para-Goom. In order to get to the Gray Chest, Wario must take the second zipline handle that travels down and right, which causes him to roll through the damaged blocks. From there, the Gray Chest is down the ladder and to the left.

The Explosive Plunger Box detonates the bombs, where the bomb symbol flashes red and explosions occur, causing the bombs found in The Stagnant Swamp, Cave of Flames, and The Colossal Hole to blow up make new areas accessible.

Red Chest: Crayon (red)
The red is inside the Red Chest, which requires the Prince Frog's Glove from Out of the Woods' Green Chest to obtain. It allows Wario to swim past currents to a new area, which normally pushes him away.

The Red Key is located in the bottom area, which contains a series of currents. In order to reach the cave that contains the Red Key, Wario must go in the middle column, and then go to the left near the bottom, followed by going up, left, and then down. Within this cave, there is a Red Key and a Hammer-bot blocked off by a column of Enemy Blocks.

The Red Chest is within the cave in the main area surrounded by a loop of currents. With the Prince Frog's Glove, Wario doesn't need to ride the current to reach it. Within the cave, the room with the Red Chest is at the top-right, which can be reached by riding a series of zipline handles to reach there. Within this room, there are two Teruteru and one column of damaged blocks at the top before the Red Chest.

The red Crayon flies to the tower on the northern side of the world. The crayon is used to color one part of the area that is initially monochrome. The red crayon colors the door that serves as the building's entrance. After the area is colored by seven different crayons, the Golf minigame there can be played.

Green Chest: Red Chemical
The is inside the Green Chest, which requires the Sapling of Growth from A Town in Chaos' Blue Chest to obtain. This causes the Octohōn to grow big and thus able to break the grate that it is originally trapped behind.

The Green Key is located in the area to the left, after the Octohōn breaks the grate that originally blocked the way. Within this area, there is a current at the top of the area, while the area at the bottom doesn't have them. The Green Key is towards the left at the bottom, where there are bubbles and Haridama to avoid in order to reach the key.

The Green Chest is within the cave in the main area surrounded by a loop of currents. Within this cave, the room with the Green Chest is in the middle. To reach it, Wario must go to the top row of ziplines and drop towards it, past the first set of spikes. Within this room, there is a Silky. Wario must bring the Silky to the top, to allow it to trigger Ball o' String Wario to break part of the pillar that is treated as a Yarn Block. After reverting, Wario must climb down a series of ladders to reach the Green Chest.

The Red Chemical from this chest and the Blue Chemical from The Steep Canyon's Blue Chest are both required to soften the ground below 5-ton blocks in this level and The Vast Plain so that they sink, allowing access to areas previously blocked by them.

Blue Chest: Clubs Crest
The is inside the Blue Chest, which requires both the Red Chemical from this level's Green Chest and the Blue Chemical from The Steep Canyon's Blue Chest to obtain. The chemical reaction after pouring both of them on the ground causes it to soften, sinking the 5-ton block above it to enable access to the area behind it.

The Blue Key is located in a cave past the 5-ton block on the right. Within this cave, there are Hebarii, Para-Gooms, and Brrr Bears, as well as many damaged blocks. The Blue Key itself is at the top-left, which can be reached by going right, then up the ladder, and then to the left.

The Blue Chest is within the cave in the main area surrounded by a loop of currents. Within this cave, the room with the Blue Chest is at the top-left corner. To reach it, Wario must go to the top row of ziplines and travel to the left, while avoiding the spikes along the way. Within this room, there is a Doughnuteer in the ladder above. To access the chest, the Doughnuteer must be thrown at the Enemy Block to break it, and then use its doughnut to trigger Fat Wario to break the nearby doughnut blocks, so that Wario can access the chest after the reaction wears off.

The Clubs Crest does not affect the world in any way.
