The Howler Monkey
From Monkey Island wiki
The Howler Monkey is Coronado De Cava's ship. It is made entirely of rubber trees, making it nigh-invicible in ship-to-ship combat. De Cava takes the ship on the journey to find La Esponja Grande in his attempt to prove his love for the Voodoo Lady. The ship is swallowed by a giant manatee and Coronado lives in its mouth while the crew parties in the stomach. The ship sits in a pool of bile until newcomer Guybrush Threepwood purges the manatee. Back on the seas, the Howler Monkey proves seaworthy enough and even engages in battle against Guybrush aboard the Screaming Narwhal. Unable to sink it, Guybrush calls upon the manatee, who swallows the ship and its crew once more.
