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 will be accessible after Wario collects both of the Snow Storm Spell Book (The Peaceful Village) and the Freeze Cane (The Grasslands) and freezes the water in this large sea.

The main area is full of ice blocks and Brrr Bears that try to stalk Wario by shooting him with ice and turning him into an Ice Skatin' Wario. There is some unfrozen water at the area's bottom, where an underwater door is found there. It also has blocks that can only be destroyed by a rock (which is found in the area as well). Another area is found when Wario enters a door located on the left side of the main area. Here, Wario must use his Snow Form to break snowman blocks and process. Wario can also explore some other areas via warp pipes and doors, and of course, by getting more power-ups.

Grey Chest : Spiked Helmet
To get this treasure and have the ability to break blocks using his head, Wario must first find the grey key located behind a wall. To access it, Wario must simply break the wall. As for the chest, the hero must get to the right side of the main area by avoiding Brrr Bears and simply open the treasure chest.

Red Chest : Magic Pot
To get this treasure, Wario must first get its key. The key is located in a room full of blue birds. However, solid blocks block the door of this room. To get there, Wario must find a rock in the first area and break the blocks with it. When done so, the door is accessible. Wario must simply make his way to the top of this room and grab the red key.

As for the chest, it is located in the snowman blocks area that its door is blocked by solid blocks as well. Wario must grab the rock another time and break the blocks near the entrance. When done so, the hero must enter the area.

Here, Wario must turn into a Snowman Wario using the falling snowballs. And make himself bigger by rolling on the first slope. This will allow him to break the lower part of a wall and reach another area. The same has to be done here. By using the snowman form, Wario will roll on a slope and becomes big enough to destroy the snowman blocks in the first area and get the treasure.

Green Chest : Flame of Truth
To get this treasure, Wario must first enter the underwater door in the main area of this level. When done so, he'll find himself near the treasure chest. The chest is accessible, however, Wario must get its key first. To do so, he has to enter the other underwater door. Then, he has to break the wall and enter the large warp pipe.

Here, Wario must avoid the Brrr Bears and activate the switch located on the left. This will freeze the water in the treasure chest area. After doing this, Wario must return to the first area by falling from the switch area. Now that the water is frozen, the key is reachable.

Finally, Wario should return to the switch area and hit the switch again to unfreeze the water, and open the treasure chest.

The Flame of Truth, along with the Lantern of Truth make the Castle of Illusion appear on the east side.
