From Monkey Island wiki
The Screaming Narwhal was constructed by concerned citizens on Flotsam Island out of the debris that came ashore on the island, giving it a strange look. However with the winds blowing into the island it is still impossible to sail away.
The Screaming Narwhal has a strange and unique tradition regarding its captaincy. For one to become captain of the Narwhal, one has to knock the previous captain off the deck. Reginald Van Winslow is the captain of the ship for several years, claiming that no one is "man enough" to challenge his captaincy. Guybrush is able to knock Winslow from the deck by using a small bomb and a crafty use of a washing line, becoming the new captain of the ship.
Layout and Features
The Screaming Narwhal consists of of an upper deck, a small higher deck for the navigator of the ship, a crow's nest, the quarters, and a lower deck (though, the latter two are not seen in-game). There may multiple lower decks, but due to the small size of the ship, it is doubtful.
Some of the notable features of the ship are the bowling pin on the ship's wheel, the sails patched together from multiple fabrics, the map nailed outside the ship's quarters, and the weathervane at the bow of the ship (placed there at the end of "Launch of the Screaming Narwhal").
Guybrush travels with Winslow, who offers to return to the ship as a First Mate and Navigator of the ship. All Guybrush has to do is point at a map depicting the Gulf of Melange and Winslow is usually able to navigate him there.
Guybrush once invited pirate hunter Morgan LeFlay to join the crew of the Screaming Narwhal, but she declined without a second thought.
After turning the winds outward of Flotsam Island, Guybrush is able to travel to the Rock of Gelato in an attempt to find Elaine and LeChuck. He is confronted however by the pirate hunter Morgan LeFlay and forced to duel her. Guybrush manages to do significant damage to the ship (which he blames on LeFlay), cracking the mast by releasing a carefully placed counterweight.
They sail to the Jerkbait Islands, where Guybrush manages to have the mast repaired at a shop on Spinner Cay. After this Guybrush is able to travel around the Jerkbait Islands and the Gulf of Melange, completing errands and resolving the pirate siege of Spinner Cay.
After following a group of mysterious sea creatures summoned by the Vaycaylian Summoning Artifacts, the Screaming Narwhal is swallowed by a giant manatee when Guybrush and Winslow are distracted by LeFlay, who has boarded the ship by surprise once again.
After Guybrush finds the manatee's missing cochlea, he and the other inhabitants of the manatee are able to exit aboard the Screaming Narwhal. No damage comes to the ship throughout the process.
After finding La Esponja Grande, Morgan LeFlay betrays Guybrush's new-found trust in her by knocking out both him and Winslow. She commandeers the ship and sails it back to the ocean surrounding Flotsam Island.
The Screaming Narwhal engages Captain McGillicutty's ship in battle after he captures the Vaycaylian Chieftain from Spinner Cay. McGillicutty's cannon fire ends up destroying his own ship as the cannonballs rebound off the Narwhal's new rubber tree mast.
The Narhwal was also one of several ships to attack LeChuck's ship in an attempt to thwart the pirate god, the ship being manned by Winslow at the time.
- In the PS3 version of "Launch of the Screaming Narwhal", Guybrush can repeatedly throw both lit and unlit mini-bombs at Winslow and the Screaming Narwhal prior to repeatedly throwing the Pyrite Parrot atop the Ancient Portal in the Flotsam Jungle in order to earn the player a "Bats Right, Throws Lame" bronze trophy (a spoof on the idiom "Bats right, throws left") in the PlayStation Network Trophy Achievements. If he manages to summon the Vaycaylian Wind Gods to calm the winds and escape with Winslow and the Narwhal, the reward is a silver trophy labeled "The Winds of Freedom Blow" (a reference to the Stanford flag motto, "Die Luft der Freiheit weft" ("The wind of freedom is blowing"), which is also parodied on the flag of the Flotsam Island Courthouse); and if Guybrush manages to trap his Pox-infected hand and order Winslow to set sail for the Rock of Gelato, the reward is the first gold trophy labeled "Many Unhappy Returns" (a spoof on the greeting "Many Happy Returns") at the very end of the chapter.
- In "The Siege of Spinner Cay", Guybrush can make Morgan angry by repeatedly looking at the mast of the Narwhal to earn the player a "She's Cute When She's Angry" bronze trophy; threaten her with his hook after using it in place of his lost hand as one of the goals needed for the "Talk to the Hook" bronze trophy; and get her off the Narwhal for the "Give Her a Hand" silver trophy. Later on, if Guybrush manages to sink McGillicutty's ship using a rubber tree mast in the Narwhal to repel McGillicutty's cannon fire, the reward is a "Mighty Merperson Rescuer" silver trophy; and the player is rewarded a second gold trophy labeled "The BIG Finish" after a cutscene with the manatee swallowing the Narwhal at the very end of the chapter.
- In "Lair of the Leviathan", if Guybrush tries every locket combination on Coronado De Cava before possessing the Voodoo Lady, the reward is the "Lord of the Locket" silver trophy; and when Guybrush manages to fire the head of a sea creature to summon the manatee to re-swallow De Cava and his remaining crew that are in the Howler Monkey, the reward is a third gold trophy labeled "Feed the Beast".
