Ghost Pirates of the Sea-erra Madre

You hear the siren's songs outside and decide to push the button.

Upon pushing the button the entire ship seems to shake and rise at an incredibly fast rate. The ship launches out of the ocean and the water drains out of the room you're inside before solid metal shutters slam shut over the doors and windows.

"What's going on?" you cry, trying to hold on.

"You've activated my spaceship," says the skeleton. "I'd been cursed by the merfolk, so was unable to do it myself, but now we're returning to my planet!"

It's not Atlantis, but going to another planet seems pretty neat too.
