Lunar Whale The Lunar Whale , also known as the Big Whale and Magical Ship , is the ultimate airship in " Final Fantasy IV " , bestowed on the party with the aid of the elder of Mysidia . The " Lunar Whale ' s " sprite is three to four times the size of the other airships , and it moves slower . Due to its size the ship cannot land in some places the " Falcon " and the " Enterprise " can and it is unable to enter the crater to the underground — if the player attempts to land the airship and enter the crater , the airship will lower and then rise back into the air , showing it is too big to fit . Some versions of " Final Fantasy IV " have a glitch concerning the airship , where the player may accidentally lose the airship on the Red Moon . Story . " Final Fantasy IV " . The ship was constructed by the Lunarian Kluya to travel between the Red Moon and Earth .

Thus the Mysidian Legend refers to the airship as " Birthed from womb of Dragon ' s maw , And borne unto the stars " . The Mysidian Legend was passed down in Mysidia . Giott is also aware of the legend , but refers to it as explicitly a legend about the " Lunar Whale " .

After the Mysterious Girl shatters their Crystals and declares her intent to travel to Earth , Fusoya and Golbez call the " Lunar Whale " , and Fusoya teleports Golbez aboard and sends him to Earth on it , staying behind to face Zeromus ' s Malice and his Big Bang attack .
