The Colossal Hole

The Colossal Hole is a level located in the east part of the Music Box World which appeared in Wario Land 3. It is only unlocked, along with The West Crater, after Wario uses the Tusks and Green Flower to make the volcano erupt.

The Colossal Hole is an underground level inhabited by Omodon enemies who turns Wario into Flat Wario if they manage to crush him. In this case, Wario must simply get caught by a blue Omodonmeka to return to normal. In the bottom of the level, there are Pneumos that turn Wario into Puffy Wario, allowing him to return to the top. A golf minigame and minigame block are found here as well. There is an area outside the hole, reachable via owl. It has a sun/Mr. Moon, Brrr Bears and a Spear-bot.

Like all the levels in the eastern part, this level is only visitable at night time. However, after Wario restores the Sun Medallion, he can visit it anytime. The only difference is the owls who sleep during the day, allowing Wario to use them. At night, those owls are flying in the air and it is impossible for Wario to catch them unless he has the High Jump Boots. This is also one of many levels that has bombs in it; when Wario blows them up with the Explosive Plunger Box found in Beneath the Waves, new areas become accessible. One such area is full of snakes, though they are not summoned by the Flute.

Gray Chest: Left Glass Eye
The Left Glass Eye in the Gray Chest is located at the left side of the level. Wario must first use his puffy form to get the Gray Key.

The jewel is a set of two items. The Right Glass Eye can be found in The West Crater. Together they can open the blue door with a snake imprinted on it, which can be found in the Tower of Revival. This allows Wario to progress further in that level.

Red Chest: Air-Pump
The in the Red Chest requires the Garlic treasure from the Tower of Revival. Wario must play a game of golf, then go down the ladder at the far left of the mini-game door. Then, he must avoid the Omodonmeka, break the solid blocks, and enter the door at the far right.

There, Wario must take the Spearhead and break the floor to reach the Red Key. After doing that, he must return to the area with the Omodonmeka and use his puffy form to avoid the spikes and head up. He then has to enter the door at the upper left, which was previously blocked off by a mini-game block. From there, he can break the solid blocks and open the chest.

The Air-Pump makes the ice blocks rise in The Pool of Rain and Bank of the Wild River.

Green Chest: High Jump Boots
The High Jump Boots power-up in the Green Chest requires this level to be visited in daytime, which is only possible after restoring the Sun Medallion and clearing the darkness. Wario must use the first owl to reach the second one, which he must use to avoid the spikes and reach a door leading to an area outside the hole.

Here, Wario must run until he finds two vertically placed Bonfire Blocks. To break them, he has to turn into Hot Wario using the sun in the area. Once broken, Wario can reach the Green Key.

After getting the key, Wario must find two horizontally placed Bonfire Blocks and break them the same way he did with the other ones. Then, Wario must simply open the chest to discover his new High Jump power-up. This opens up new areas in The Grasslands, The Stagnant Swamp, and Cave of Flames.

Blue Chest: Locomotive
The in the Blue Chest requires blowing up the bomb found in this level using the Explosive Plunger Box from Beneath the Waves. Then, he has to use the first owl to get above the hole. The door is now accessible. Upon entering the door, Wario will find himself in an area full of snakes, which he can use to get the Blue Key and reach the area where the Blue Chest is.

Getting the Locomotive does not affect the world in any way.
