The Big Bridge

The Big Bridge is a place located in the south part of the Music Box World in Wario Land 3. When Wario goes to the south part for the first time, the bridge is not down. Upon using the first music box found in The Grasslands, it becomes accessible.

The level itself is a long gray bridge. Wario has to cross it to get some treasure. Upon stepping on it, Tadpoles will try to stalk Wario and send him to the entrance.

There are also some doors underwater that the player can access.

Gray Chest: Magic Seeds
The Magic Seeds in the Gray Chest requires the Gray Key located on the left of the entrance. Wario must then cross the bridge by avoiding a series of Tadpoles. The Gray Chest is just across the bridge.

The Magic Seeds will make vines grow in The Pool of Rain, The Grasslands and The Vast Plain. It allows Wario to open new paths.

Red Chest: Crayon
The in the Red Chest requires Wario needs to get the Swimming Flippers found in the Tower of Revival. To get to the Red Chest, he only has to enter the door located deep underwater and avoid the Brrr Bears to get the Red Key and open the Red Chest.

Once the crayon has been collected, it flies to the tower on the north side of the world. The scene is initially monochrome, but gains another color for each crayon Wario manages to find. There are seven crayons in total hidden throughout the game, and once Wario finds all of them, he will be able to play the golf mini-game there at any time the player desires. The cyan crayon colors the sky of the hill that separates the north side from the south side.

Green Chest: Pokémon Pikachu
The in the Green Chest requires Wario to pick up the red barrel located in the left side of the entrance, then use it to break the blocks at the right side of the level. The Green Key is in a room that Wario can enter using an underwater door.

As for the Green Chest, it is located by entering the door accessible after breaking the blocks with the barrel. Wario has to play a game of golf and raise the mini-game block which leads to the Green Chest.

The treasure serves no purpose. It refers to the Pokémon Pikachu virtual pet.

Blue Chest: Lantern of Truth
The in the Blue Chest requires the Spiked Helmet. First, he must enter the door located in the left side of the level and search for the Blue Key. When found, he has to go underwater and break a series of blocks using the Head Smash (and his bubble reaction). When done so, he has to climb the ladder located in the right side of the underwater area. Now that the blocks are broken, he can access the Blue Chest.

The Lantern of Truth, along with the Flame of Truth, makes the Castle of Illusions appear on the east side.
