Mammoth

The Mammoth is a ship used by the Beasts Pirates. It is captained by Jack.

History
The Ship is first seen in the seas of New World, watching from distance as several marine ships transport Donquixote Doflamingo to Impel Down. On board crew members ask their captain if he's sure about his plan to which Jack angrily confirms stating they have to retrieve Doflamingo no matter what. Jack went through with his plan of attack managing to sink two of the four escort ships before being defeated by the marines led by Admiral Issho and former Fleet Admiral Sengoku. It is stated in the newspapers that Jack was killed in his defeat, leaving the Mammoth's fate unknown.

Ship Design
The ship's figurehead appears to be that of a mammoth's head, hence the name. It also has the Beasts Pirates' Jolly Roger located on the main sail.
