Bunny Link is a form of Link in A Link to the Past, appearing as a fluffy pink rabbit wearing a green tunic. Link is transformed into this form as a result of entering the Dark World, which changes people to reflect their true nature.
When Link climbs Death Mountain on his quest to find the three Pendants of Virtue, he finds a portal in the north-east side of the mountain that teleports him to the Dark World's counterpart. Without the Moon Pearl, Link finds himself transformed into Bunny Link. A Bully and his Friend nearby explain to him how the world transforms anyone who enters in reflection of their true nature. Once Link obtains the Moon Pearl from the Tower of Hera, he will no longer transform into Bunny Link whenever he enters the Dark World.
In certain Dark World dungeons, Link can temporarily be transformed into a rabbit regardless if he has the Moon Pearl by coming in contact with rotating, golden star-shaped objects called Rabbit Beams. However, this change wears off after a few seconds or after being hit by an enemy.
- In the original game, even after obtaining the Blue or Red Mail, Link will continue to wear a green tunic as a rabbit. However, in the GBA remake, Link retains the color of his tunic.
- Ravio from A Link Between Worlds may be a homage to Bunny Link, as his mask has a rabbit motif and he originates from Lorule, a land that is nearly identical to the Dark World.

- "But if you have a ball called the Moon Pearl, you can keep your original shape here." — Bully's Friend (A Link to the Past)
