Haunted Rock is the cave you will find in Haunted Isle. You will have to go in to chase after Team Fusion while Blake fixes the boat that will get you out of there.

Head up to the final cave to face Pikachu who is now lvl 25. He has Quick Attack, Agility, Thunderbolt and Draining Kiss(?).
After defeating Pikachu, it gives you the Delusifier which allows you to see past illusions. Pikachu tells you that there are illusionary rocks in the caves below blocking you from reaching his superiors.
Head back to the lowest level of the cave and go into the first room (if you went in previously, you would have reached a dead-end). At the far end of this room, there are two strange looking rocks. Interact with them and you will use the Delusifier to see through the illusion and continue north into the next room.
