Shakedown Schooner is the Shake King's pirate ship in Wario Land: Shake It! It is the last location Wario must visit, and it is here that Queen Merelda and the Bottomless Coin Sack are being held.
The Shakedown Schooner appears after Wario collects the five Boss Emblems from Rollanratl, Hot Roderick, Chortlebot, Bloomsday, and Large Fry. As such, Wario is able to fight the Shake King.
