By trading a long list of items, the player will eventually be rewarded with a useful item such as a better sword, new tools or even numerous Pieces of Heart. However, due to their status as sidequests, they are not necessary to complete the game, except in the case of Link's Awakening, where several items, including the final reward, are mandatory.
As Link tries to help a character, he may receive an item that becomes useful for someone else; when Link gives the newer item to the right character, he receives in turn another item that is destined to yet another character; a trade sequence takes form when this process is repeated continuously, thus resulting into a long string of exchanges that ultimately lead to a powerful item. For natural reasons, the traded items generally have one-time uses, and therefore one-time appearances.
In Link's Awakening, the Trading Quest begins by obtaining the Yoshi Doll from the Trendy Game in Mabe Village. It eventually ends with Link obtaining the Magnifying Lens that allows him to read the Book Dark Secrets And Mysteries Of Koholint inside the Library which tells him the directions to navigate the Egg Maze.
