You’ll find Blastoise’s Mega Stone (Blastoisinite) in the top right corner of the front deck of the S.S. Tidal. But before you can board this ship you’ll need the S.S. Ticket, which you get after finishing the Delta Episode.

Once you have the ticket, you can access the previously-inaccessible S.S. Tidal and get your Mega Stone.

Location

To get started, Fly to a nearby harbor in either Slateport or Lilycove City.

Step 1: Present your ticket to the attendant in the Harbor and select the opposite harbor destination, depending on which harbor you’re in. So basically:

  • Choose Lilycove City if you are departing from Slateport Harbor
  • Choose Slateport City if you are departing from Lilycove Harbor

Step 2: Once you’re on the S.S. Tidal, proceed down the hallway on the left.

Step 3: Eventually you’ll trigger a cutscene between Mr. Briney and Drake (if this is your first time here).

After that, continue westward.

Step 4: Exit the hallway on the far western side – this will bring you out to the deck of the ship.
