Walkthrough
  1. 1
    Upon entering Diglett's Tunnel, head south to meet Kahuna Olivia. She allows passage after you show her 3 new Z-Crystals.
  2. 2
    Follow the tunnel south to a fork. Head east first along the narrow path.
  3. 3
    At the next fork, the upper path leads to a trainer (Worker Frank), the lower path avoids him.
  4. 4
    After Worker Frank, grab the Dusk Ball in the corner.
  5. 5
    Return to the initial fork and head west. Use Stoutland's 'Search' ability near rocks to find an Escape Rope.
  6. 6
    At the corner, search rocks above for a hidden X Attack.
  7. 7
    Switch to Tauros. North-west are stairs. Before climbing, smash rocks above the stairs with Tauros to find a Fire Stone behind them. This stone evolves Growlithe and Eevee (into Flareon).
  8. 8
    Climb the metal stairs. You'll see Aether Foundation employees and Olivia.
  9. 9
    Follow the slope south, then east. Pick up the Hyper Potion next to a wheelbarrow.
  10. 10
    For more battles, head south through a narrow path.
  11. 11
    Past the narrow path, carefully move west past a circling Pokémon, then north.
  12. 12
    At the end of this path, a large boulder is to the left, and a trainer (Worker Jeff) is to the right, blocking a ledge.
  13. 13
    Defeat Worker Jeff and his two Diglett. They are weak to Water, Fire, Ground, and Fighting.
  14. 14
    Jumping from the ledge east of Jeff returns you to the top of the stairs near the Hyper Potion.
  15. 15
    From the wheelbarrow area, continue east. As the path widens, slow down.
  16. 16
    Near rocky mounds patrolled by a worker (Worker Vaclav), search a crate to the right of a wheelbarrow for a hidden Nugget.
  17. 17
    Avoid Worker Vaclav by heading along the north side of the mounds when he's in the south-west corner, or by running east.
  18. 18
    Defeat Worker Vaclav, who uses an Archen (weak to Water, Electric, Ice, Rock, Steel). Its offensive stats decrease below half HP.
  19. 19
    Head south-east from the rocky mounds towards the tunnel exit.
  20. 20
    Before exiting, you must face a Multi Battle against two Team Skull Grunts with Hau as your partner. They use Salandit and Ekans. They are weak to Psychic and Ground-types, and Water/Rock for Salandit.
  21. 21
    After defeating the Grunts, Hau gives you a Max Ether.
  22. 22
    You can now leave the tunnel to reach Route 9.
