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 Gears 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 cannot see. This is one of the three levels where a snake can be summoned using the Flute. This is one of the levels with a music box, which is obtained by defeating this level's boss, Wormwould.

Gray Chest: Yellow Music Box
The Yellow Music Box from the Gray Chest is needed to unlock The Big Bridge. In the cave at the rightmost part of the grassy surface, Wario has to use the Flat Wario form and avoid the Omodonmeka enemies to reach the Gray Key. Then he has to get out of the cave to go to the entrance at the highest point in between this exit and the door before it. In this entrance, Wormwould is below and is needed to be defeated to make vines grow and reach the Gray Chest. The music box closes the two halves of the drawbridge in the The Big Bridge.

Red Chest: Truck Wheel
The Truck Wheel, also known as the Wheels , require the Magic Seeds found in The Big Bridge. After acquiring the treasure, he can access the vine grown at the far right. The Red Key to access the Red Chest is above the staircase-like blocks near the beginning.

The vine to access the cave is below the rightmost ladder and to the right, where there are three Nobiiru on the way up the vine to the entrance. Within this case, the Red Chest is blocked by a mini-game block. The Golf Minigame to open the entrance requires travelling around, first by going up the ladders, then smashing the breakable pillars towards the right, and then using a Smash Attack through the breakable blocks downwards and a Dash Attack to the blocks to the left. To get back from that point, jump up the platforms on the left, then break the breakable blocks on the left, and then climb down the ladders to reach the beginning.

The Truck Wheel makes the carts in The Volcano's Base work.

Green Chest: Magic Wand
The Magic Wand in the Green Chest requires the Flute found in The Stagnant Swamp that summons several snakes in the world. To get to the snake in this level, there are two platforms without grass that leads towards a snake pot to the left. From the snake's head, there is a door in the tree trunk to the left and another door up the ladder. From the upper door, the platforms are required to reach the Green Key. If the Green Key failed to be collected, then exit through the lower door above water and then climb up the ladder to the upper door to attempt again. To get to the Green Chest, Wario must travel underwater to navigate the path while avoiding bubbles.

The Magic Wand, along with the Blue Book found in The Peaceful Village, will freeze the sea found in the east side of the world, turning it into The Frigid Sea.

Blue Chest: Fighter Mannequin
The in the Blue Chest requires the High Jump Boots from The Colossal Hole. First, Wario must make his way underground until he reaches a high ledge. He can now get there using a high jump and enter the door. Here, Wario must go up the ladder and avoid the Silkies until he reaches an area with a barrel and several Applebies. Wario must use the barrel (it respawns if it's gone) to defeat some of them to be able to climb the ladder with less apples thrown at him, and then enter the door. Here, he must clear the breakable blocks and use a Dash Attack to bring the furnace above the thin platforms, and then let the Hammer-bot trigger Bouncy Wario which allows him to reach the Blue Key by jumping off the furnace. After acquiring the key and exiting the room, Fat Wario must be triggered by one of the Applebies' apples, so that the doughnut blocks below the area can be broken by Wario. After that, the Ball o' String Wario must be triggered to break the yarn block to open access to the left room. In the left room, the breakable blocks are required to be broken to make way for Ball o' String Wario to be able to break the other yarn block leading to the Blue Chest.

This treasure does not affect the world in any way.
