The Colossal Hole (E4) is the deep eastern cavern that opens after the volcano set erupts a path from The Frigid Sea. Use the finder below for every Gray, Red, Green, and Blue chest, the permanent High Jump Boots, the Left Glass Eye Tower of Revival pair, all eight Musical Coins, and exact room-map links for Day/Night and each map variant.
FIRST CLEAR PRIORITY
Open the Green Chest for the High Jump Boots
Carry the Green Key to the Green Chest in room 13 and take the High Jump Boots. They permanently raise Wario’s jump height and open S5 Cave of Flames V2, S1 The Grasslands V4, and E1 The Stagnant Swamp V3. On the same visit, grab the Gray Chest Left Glass Eye to pair later with West Crater’s Right Glass Eye for Tower of Revival V2. Return for Air Pump, Locomotive, and Musical Coins as Garlic, Sun Medallion, or Explosive Plunger Box unlock harder variants.

ABILITY · HIGH JUMP
How the High Jump Boots work
High Jump is permanent ability power-up level 7. After the Green Chest, Wario’s jump height increases, which opens ledges that were previously out of reach in many levels. Use it whenever a high platform or ceiling gap seals a treasure route.
| What you get | Where | What it unlocks next |
|---|---|---|
| High Jump (reach high ledges) | E4 Green Chest · High Jump Boots | New vertical routes inside many levels |
| Cave of Flames map variant 2 | S5 after High Jump Boots | Extra revisit routes in Cave of Flames |
| The Grasslands map variant 4 | S1 after High Jump Boots | Extra late Grasslands layout |
| The Stagnant Swamp map variant 3 | E1 after High Jump Boots | Extra Stagnant Swamp revisit routes |

| Piece | Level · chest | Together unlock |

UNLOCK · OVERWORLD
How to open The Colossal Hole
Volcano set erupts the Frigid Sea path
Collect the Blue Tusk (W2 Volcano’s Base Blue Chest), Red Tusk (S4 Steep Canyon Red Chest), and Green Flower (E1 Stagnant Swamp Red Chest). Completing that volcano set triggers the eruption: it opens W6 The West Crater and creates a route from E2 The Frigid Sea into E4 The Colossal Hole.
Once E4 is available, prioritize High Jump Boots, then Left Glass Eye for the Tower of Revival pair. Later, the Torch from Castle of Illusions burns eastern vines from the Colossal Hole path into Forest of Fear.

| V2 | Garlic (S3 Tower of Revival Red Chest) | Powered dash opens more revisit routes inside E4. | Open Day map |
| V3 | Sun Medallion Top + Bottom (N6 + W1) | Late-east layout after both medallion halves are collected. | Open Day map |
| V4 | Explosive Plunger Box (W5 Beneath the Waves Gray Chest) | Late-game layout for remaining E4 routes and Musical Coins. | Open Day map |

FAQ
The Colossal Hole FAQ
How do you open The Colossal Hole in Wario Land 3?
Collect Blue Tusk, Red Tusk, and Green Flower to complete the volcano set. The eruption opens The West Crater and creates a path from The Frigid Sea to E4 The Colossal Hole.
How do you get the High Jump Boots / high jump ability?
Open the Green Chest in The Colossal Hole. On the default Day map the Green Key and Green Chest share room 13. High Jump permanently raises Wario’s jump height so he can reach higher ledges.
What does High Jump unlock on the overworld?
Besides the ability itself, High Jump Boots unlocks Cave of Flames map variant 2, The Grasslands map variant 4, and The Stagnant Swamp map variant 3. Use those revisits when chest or coin routes in those levels are still sealed.
What does the Left Glass Eye do?
It pairs with the Right Glass Eye from The West Crater Gray Chest. Both eyes unlock Tower of Revival map variant 2, the state used for Garlic and other S3 routes.
What does the Air Pump do?
Air Pump from the Red Chest unlocks Bank of the Wild River map variant 4 and The Pool of Rain map variant 4. Grab it when you need late water-level layouts.
How many Musical Coins are in The Colossal Hole?
Eight—the same as every other level. Use the coin table above or the full Musical Coins Finder if you are missing one for 100% side goals.
Does The Colossal Hole have a boss?
No named boss arena is tied to The Colossal Hole. The level’s main progression value is High Jump Boots, Left Glass Eye for Tower of Revival V2, and Air Pump for late water layouts.
Is it Gray Chest or Grey Chest?
Both spellings refer to the same chest. This guide uses Gray in player-facing text and also matches grey in search.
