Moon Pearl

The Moon Pearl is a shining gem which allows Link to retain his normal shape while in the Dark World. Other humans entering the Dark World are transformed into shapes which reflect their "True Nature", or personality. This is shown by the pair of men on Death Mountain, as well as Link himself. The bully is transformed into a demon-like creature because of his devilish nature, and the other man turned into a ball because he could never make up his mind. Link's "true nature" is apparently a cute little pink bunny rabbit, probably due to his kindness and compassion. (This is commonly referred to as Bunny Link.) This Pearl appears in A Link to the Past. Another Moon Pearl appears in Four Swords Adventures, and is not one item, but several items scattered all over Hyrule. One pearl will open one Moon Gate
