The Steep Canyon

The Steep Canyon is a location found in the south part of the Music Box World in Wario Land 3. Wario cannot access this level at the beginning. However, after he retrieves both of The Anger Spell Book (the Tidal Coast) and the Anger Halberd (Bank of the Wild River), the two will create a storm and opens the path to this level.

The level is a big canyon, with currents in its bottom. A giant fissure will be made by the Giant's Foot and Wario can enter a big cave via that fissured wall. In this cave, Wario can find Jellybobs and some spiked blue slimes. At the top of this canyon, there are two owls that Wario can use to get past some obstacles and reach higher areas. This is also one of the three levels that has an iron wall in it. After being rusted by the Rust Spray found in Castle of Illusions, Wario can access some new areas. The first one is inhabited by Spearheads. The second one has three torches to light, just like in Tower of Revival. The third one has two Beam Robotas in it, a minigame block and a golf room.

Grey Chest : Red Gloves
To get this treasure, Wario has to make his way to the right side by breaking walls and avoiding the Fire Robotas and the water hands.The key is at the far right.

As for the chest, he has to roll from the right side of the level and avoid the Prince Froggy to break the rocks in the left side and access the Grey Chest.

The Red Gloves allows Wario to lift small enemies.

Red Chest : Conch Artifact (red)
Wario needs to get the Stone Foot which shakes the ground and fissures The Volcano's Base along with this level to manage to get this treasure. He has to enter the fissure and use the Puffy Wario form to get the red key. Then, use it again and avoid the spikes to get to the platform where the Red Chest is.

When three Conch Artifacts are collected, they cause the Volcano to erupt and make a hole in the east side named The Colossal Hole and open the path for The West Crater.

Green Chest : Telephone
To get this treasure, Wario must get the Frog Prince's Gloves from Out of the Woods. First, he has to go to the Red Key's room and fall into the water. He has to keep swimming against the currents until he reaches a warp pipe. In this room, Wario has to ground-pound the ground to make the spiky enemies float. He can use them a platforms to get to the top. He'll end up near the Green Chest. It cannot be opened however because he didn't get the key. So Wario has to enter the warp pipe near it.

Here, Wario has to use the owl to get past the spikes and the spark-like enemies, and grab the key in his way to a second warp pipe. When entered, Wario will end up in the red Key's room again. He has to do the same thing as before. Now that he has the key, the chest can be opened when he reaches it.

Getting the Telephone doesn't effect the Music Box World in any way.
