The Grasslands

The Grasslands is a level found in Wario Land 3. It is located in the south side of the Music Box World and it is unlocked after Wario gets the two Cog Wheels in The Pool of Rain and A Town in Chaos.

As its name implies, this level is a field and there are some holes covered with grass that Wario can't see. So the Player has to guide him carefully. This is one of the three levels where a fire snake can be summoned using the flute. There is also a worm boss that Wario fights named Wormwould. When it's defeated, Wario can get the first music box.

Grey Chest : First Music Box
To get the first music box and unlock The Big Bridge, Wario has to use the Flat Wario form and avoid the UFO looking enemies in a cave to reach the Grey Key. Then, he has to get out of the cave and defeat Wormwould to make vines grow and reach the Grey Chest.

Red Chest : Wheels
To get this treasure, the miracle seed found in The Big Bridge is needed. If it is in Wario's possession then he can access the vine grown at the far right. But before that, he has to get the key which is above the door near the entrance.

When Wario climbs the vine and enters the new door, he'll find himself in a cave,the treasure chest is at the entrance but it's blocked by a mini game block, so Wario has to complete a minigame of Golf then come back to the chest.

These Wheels makes the carriages in The Volcano's Base work.

Green Chest : Ice Rod
Wario needs the flute found in The Stagnant Swamp that summons the snakes to get this treasure. The player has to guide Wario to the snake found in this level. Then jump on his head so he can access to the two doors at the far left. He has to enter the upper door first and use the three red platforms carefully to get the green key. Then,he has to swim underwater by avoiding the bubbles and enter the door located there to get to the chest.

The ice rod, along with the spell book found in The Peaceful Village will freeze the sea found in the east side of the Music Box World turning it into The Frigid Sea.
