Journey to Find Oneself: Link has long defeated the evil Ganon, but Hyrule merely enjoyed a precautious peace, its citizens wondering when the next threat would arrive to end the tranquility. Feeling in need of enlightenment, he embarks on this journey for foreign lands.
Kleptomaniac Hero: In addition to Link's usual kleptomania, he can now outright steal things from the shop.
Only Sane Man: Indeed, because he's the only real man in the whole game.
The female lead in Link's Awakening, of whom Malon is an Expy. A singer who rescued Link when he washed ashore, and later teaches him the "Ballad of the Wind Fish" which is critical to waking the Wind Fish.
However, she is SCARILY encouraging of Link abusing Cuccos if you do it for long enough. Probably because, once she starts encouraging you, if you keep doing it, the Cuccos will start attacking you like they usually do.
Guest Star Party Member: At one point you are required to take Marin with you to wake up a walrus in order to continue with the main quest.
Japanese Honorifics: The animals of the Animal Village refer to Marin as Marin-chan. This is localized in English as the nickname Little Marin.
Manic Pixie Dream Girl: Apart from the fact that she literally is a "dream girl", she qualifies. Life virtually revolving around the protagonist? Check. Quirky personality? Check. ("Dig it! Dig to the center of the earth!") Of course, Link doesn't need convincing to be adventurous.
Missing Mom: In this game and all her future incarnations. In most games, she still has a Mario look-alike dad, but in Majora's Mask, Cremia and Romani don't even have a dad.
Temporary Substitute: Fills in for Princess Zelda in the only Legend of Zelda game where Zelda doesn't appear.
Winged Humanoid (in the black-and-white version), Animorphism (in the DX version): Marin's reward if you get a No Miss Clear is to have her wish granted and either be able to fly like a seagull or become a seagull.
The father of Marin who collects mushrooms.
Baleful Polymorph: At one point he's turned into a Raccoon (or Tanuki in the original Japanese version). Although its not exactly baleful - once he's back to normal, he recalls having fun as a raccoon.
Summon Everyman Hero: While never explicitly stated, it is heavily implied nonetheless that the Wind Fish, was responsible for the storm in the game's prologue. He uses the last of his available powers to draw Link into his dream in a final desperate act to stop the nightmares taking over his mind.
