The Underground
Dig walls for treasures, stones, fossils and diamonds.
Getting in
Buy the Explorer Kit in the Cinnabar Island Poké Mart (₽5,000) — MINE joins the menu.
Digging
A wall hides 1–3 items (more as your Underground level rises) under 3–5 layers of rock.
| Tool | What it does | Energy |
|---|---|---|
| Chisel | 2 layers, 1 tile | 2% |
| Hammer | 1 layer, 3×3 | 6% |
| Bomb | 2 layers on 10 random tiles; an item it digs out is usually destroyed | 18% |
| Survey | marks a box with a treasure in it | 100% |
Tools recharge over time. Breaking rock charges a battery; at 60 charges, DISCHARGE unleashes a move that digs a big pattern without destroying anything.
What you find
Treasures (sell for diamonds), evolution stones, shards, fossils (hatch in the Day Care or revive at the Cinnabar Lab) and, later, plates. Stones, shards and fossils trade 3 → 1 within their kind.
Kinds of mine and experts
After a wall is cleared, SEARCH picks the next kind: Chaos Cavern (anything), Treasure Trove, Fractured Quarry (shards), Ancient Excavation (fossils), Evolution Nexus (stones). Underground Experts dig for you while the game is open and keep a share of what they find as pay.
