The Big Bridge

The Big Bridge is the second level on the southern side of the music box world in Wario Land 3. After obtaining the Yellow Music Box found in The Grasslands's Gray Chest and its tune is played, the drawbridge closes, enabling Wario to access this level.

The level itself has a long gray bridge. If crossing the bridge to the right, Tadpoles will leap out from the water to attempt to knock Wario and send him to the left. There are rooms on each side of the bridge, as well as under it.

Gray Chest: Magic Seeds
The Magic Seeds is in the Gray Chest. It is available as soon as the level is unlocked.

The Gray Key is located on the left side from the beginning, near the barrel.

To get to the Gray Chest, Wario must cross the bridge while avoiding a series of five Tadpoles. At the end of the bridge, the chest is nearby.

The Magic Seeds make vines grow in The Pool of Rain, The Grasslands and The Vast Plain. The newly-grown vines allow Wario to reach high places in those levels.

Red Chest: Crayon (cyan)
The in the Red Chest requires the Swimming Flippers found in the Tower of Revival's Gray Chest. It allows Wario to swim in the water under the bridge, allowing him to go into an underwater room.

The room to the Red Key and Red Chest is underwater, which requires going to the end of the bridge to break the block with a Smash Attack. From there, Wario must jump over the wall to the left, and then swim downwards while avoiding the Haridama to reach the door.

In this room, there are multiple Brrr Bears. To get to the Red Key, Wario must go to the top and then break the block to the right within the corridor. To get past the Brrr Bear in this corridor. The Brrr Bear to the left is needed to trigger Ice Skatin' Wario to slide to the right, and then drop in the gap to reach the Red Key. The Red Chest is past the gap, which requires returning to that point. To get back to the point, Wario needs to go left and break the blocks near the Musical Coin to go back to the water, and then climb back to that point.

The cyan Crayon flies to the tower on the northern side of the world. The crayon is used to color one part of the area that is initially monochrome. The cyan crayon colors the sky of the hill that separates the north side from the south side. After the area is colored by seven different crayons, the Golf minigame there can be played.

Green Chest: Pocket Pet
The Pocket Pet in the Green Chest requires the Grab Glove found in The Steep Canyon's Gray Chest. It allows Wario to use a barrel to throw at Enemy Blocks.

The room with the Green Key is underneath the end of the bridge. After breaking the damaged block with a Smash Attack, Wario must swim downwards, right, and then upwards to reach this room. In this room containing a Webber and a Spearhead, the Green Key is on the other side of the blocks. The square block to the left of the Enemy Block is treated as a series of Enemy Blocks, therefore it can be broken by throwing the Spearhead at it. Most of the rectangular block below those blocks can be broken with a Smash Attack or Dash Attack.

The room containing the Green Chest is blocked by Enemy Blocks on the right side of the bridge, which is done by bringing the barrel to the left from the beginning across the bridge to the right while avoiding the Tadpoles. In the room with the Green Chest, the chest itself is blocked by a mini-game block, requiring the Golf minigame to be cleared to open it. The path to the minigame is obstructed by Brrr Bears and Spearheads. After clearing the minigame, the way to the chest is open to the left.

The Pocket Pet does not affect the world in any way. It refers to the Pokémon Pikachu virtual pet.

Blue Chest: Lantern
The Lantern in the Blue Chest requires the Scepter from Cave of Flames's Gray Chest to purify the water in a few levels, including this one.

The room to the Blue Key is in the room above water to the left from the beginning. To get there, either use the barrel to the left to break the square block (treated as Enemy Blocks) to the left of it or swim underwater to reach the door. In this room, the way to the Blue Key contains Nobiiru near the ladder and Webbers around the top.

The room to the Blue Chest is in the underwater room to the left from the beginning. In this room, Wario must travel downwards and to the first right to break two sets of blocks above water from underwater, one of them requiring Bubble Wario to reach. After the two sets of blocks are broken, Wario must go to the left, down, and then to the right while avoiding the Haridama. On the right side, there is a third set of blocks that is needed to break to jump to the platform and to the ladder. The Nobiiru are along the ladder. At the top, if the blocks are broken earlier, Wario can crouch and jump to crawl past the gaps underneath to reach the ladder leading to the Blue Chest.

The Lantern, along with the Magical Flame from The Frigid Sea's Green Chest, creates a light that causes the Castle of Illusions to unravel its true form from a mountain on the east side, thereby making it accessible.
