In which game does Link transform into a wolf?

Link transforms into a wolf in The Legend of Zelda: Twilight Princess. The transformation occurs when Link enters areas covered by Twilight, a mysterious force from the parallel Twilight Realm.

As Wolf Link, he cannot use his sword, shield, or normal equipment, so he fights with his jaws and relies on speed and agility. The wolf form also gives him enhanced senses: he can detect scent trails, uncover hidden objects, dig passages, and perceive the spirits of people affected by Twilight.

Link eventually gains the ability to switch between his human and wolf forms. The imp-like Midna travels on his back and helps him use special attacks, leap across gaps, and warp between locations. The story connects the transformation to Zant’s curse and to the conflict between Hyrule and the Twilight Realm.

This form is unique to Twilight Princess among the listed choices. Ocarina of Time features time travel, Wind Waker centers on a flooded world, and Skyward Sword explores the origins of the Master Sword.
