Rabbit

Rabbits are a recurring race of animals in the Legend of Zelda series. The role they play varies greatly, and in similar fashion to the real world, their name seems to be interchangeable between "rabbit" and "bunny".

The Legend of Zelda: A Link to the Past
When Link enters the Dark World, his shape changes from that of a Hylian to a small, pink bunny. In this form he is unable to use weapons of any kind, and is essentially helpless. Once he returns to Hyrule, he must locate the Moon Pearl; having this mystic artifact in his possession will protect him from being transformed on subsequent visits to the Dark World.

Enemies called Rabbit Fangs appear. They are depicted as mutated, hostile rabbits that appear in the Swamp Ruins.

The Legend of Zelda: Link's Awakening
Several rabbits inhabit Animal Village on Koholint Island. When Marin comes to visit, they go to see her.

The Legend of Zelda: Ocarina of Time
The Running Man is infatuated with rabbits, who appear to be nearing extinction. Along with the fact that rabbits are never seen, this idea is furthered by the fact that the Running Man tells Link that they are a rare sight nowadays due to excessive hunting in Hyrule. Because of this, the Running Man will purchase the Bunny Hood from Link to live out his lifelong dream where he wants to "Listen to the wind with those ears, hop across the ground with those legs... Even if I can only pretend."

The Legend of Zelda: Oracle of Ages
Several rabbits appear in the Forest of Time along with many other types of animals. When Veran possesses Nayru and changes the flow of time, many of these rabbits disappear, as the disruption of the flow of time prevents them from ever being brought into existence.
