The Frigid Sea

The Frigid Sea is a location found in Wario Land 3. It is located in the east side of the music box world. It is accessible after Wario collects both of the Blue Book (The Peaceful Village's Red Chest) and the Magic Wand (The Grasslands's Green Chest), after which the water in the large sea freezes.

This level takes place over the sea with many icy platforms, and there is a waterfall on the right side of this level. During nighttime, the waterfall is frozen and effectively becomes an ice piller, but in daytime, the waterfall flows. The rooms on each end of the stage consists of snow and Snowman Blocks, while the room underwater consists of a cave that is partially submerged in water, in which the water can be frozen into solid ice.

Gray Chest: Head Smash Helmet
The Head Smash Helmet is in the Gray Chest.

The Gray Key is in the main area, where it is within the wall at the top. To get there, the wall to the left of the key must be broken with a Dash Attack, which can be reached by going up and then to the right.

The Gray Chest is located at the rightmost portion of the level, where it is to the left of the frozen waterfall. There are several Brrr Bears on the way to the chest, where they are along the platforms leading to the chest.

The Head Smash Helmet allows Wario to Head Smash destructible blocks from underneath. This opens the way for new treasures in A Town in Chaos and the Desert Ruins.

Red Chest: Teapot
To get the Teapot from the Red Chest, the Grab Glove from The Steep Canyon's Gray Chest is required.

The room where the Red Key is in requires breaking the Enemy Blocks below it to access. The only object small enough for Wario to break them is the rock at the top of the level, accessible by going right, up, and then left to it. Alternatively, if Wario has the Super Grab Gloves, one of the Brrr Bears can be used to throw at it. Within this room, there are blue birds on the way up of the icy platforms, which leads to the Red Key.

The room with the Red Chest is accessible by going past the Enemy Blocks to the left of Wario from the beginning. This requires throwing the same rock earlier to break them, or if the Super Grab Gloves is acquired, then one of the Brrr Bears can be used. The room, which is up a ladder, consists of Spearheads and a falling snowball. In order to break the Snowman Blocks before the Red Chest, Wario must use the slope in the next room to have enough momentum to break them. To do so, he must break the breakable blocks to the right so that Snowman Wario (triggered by the snowball) can use the slope to roll and then break through it. In the next room, Wario must climb up the ladder and then go left to a snowball to trigger Snowman Wario, and then use it to tumble through the Snowman Blocks to access the Red Chest.

The Teapot does not affect the world in any way.

Green Chest: Magical Flame
To get the Magical Flame from the Green Chest, the Scepter from the Cave of Flames's Gray Chest is required to make the water of the sea clear, causing a door to be visible underwater.

The Green Key and Green Chest are within the room in the sea on the left of the other side of the level. Within the room, Wario must first jump out of the water to enter the room in the other body of water. In this room, the wall can be broken on the right above water, where there is a Doughnuteer and a Warp Pipe. Up the pipe, there are two Para-Gooms and two Brrr Bears, as well as a switch to the left. Activating the switch causes the water at the bottom of the stage to become solid ice, and Wario can fall through one of the pits to return there. From there, the Green Key is to the right.

In order to access the Green Chest, the switch must be activated again, which can be done by going up the Warp Pipe next to the key, and then going left in the same room as before to do so. After that, Wario can access the Green Chest by dropping down the pit, and then going underwater in the left body of water to reach the chest.

The Magical Flame, along with the Lantern, causes the Castle of Illusions appear on the east side to make it accessible.

Blue Chest: UFO
To get the UFO from the Blue Chest, the Top Half of Sun Medallion from Sea Turtle Rocks' Green Chest and the Bottom Half of Sun Medallion from Desert Ruin's Blue Chest are required, so that daytime can happen on the eastern part of the world. For this level, it causes the frozen waterfall to melt. Alternatively, if the Prince Frog's Glove is collected from Out of the Woods' Green Chest, this treasure can also be collected regardless of the time of day.

The room that contains the Blue Key and Blue Chest is on the rightmost side of the stage, past the waterfall. During daytime, the waterfall can be bypassed normally, but during nighttime, Wario must swim past the current underwater and then climb the ladder to access the room. Within this room, there is a long corridor that consists of Snowman Blocks, slopes, and snowballs. In order to obtain the Blue Key, Wario must go to the end of this corridor while avoiding the snowballs before that. On the rightmost side of the room, the snowball up the slope must be used to trigger Snowman Wario, and then roll on the slope to provide enough momentum to reach the Blue Key.

From the Blue Key, the Blue Chest is up from the leftmost thin platform and then to the left.

The UFO does not affect the world in any way.
