Destiny's Bounty

The Destiny's Bounty was the Ninja's headquarters and main mode of transportation from 2011 to 2012. It was originally the ship of pirate Captain Soto a good two hundred or so years before the events of the main series. It was first destroyed in late 2011 by the Great Devourer, but then rebuilt by Garmadon using his Mega Weapon a couple months later in 2012. It was later taken back by the Ninja after the 2012 Ninjaball Run, and later crashed for the final time on the Dark Island, after Dr Julien piloted it into the Overlord's way to protect the Ninja.
After the Ninja left the wreckage behind, it was found by a feral Joseph, who claimed it as his home. Using the electricity left, he listened to some recordings left behind by the Ninja and learned how to speak. Years later, Joseph found Chyenne and Wu, who'd crashed in the jungle after the Ninja's current home was attacked.
