I want to know the answer to the following question:
What does Link transform into when he enters the Twilight Realm?
All the background I'm provided with is that "However, "Wolf Link" gains several key advantages in return—he moves faster than he does as a human (though riding Epona is still faster) and digs holes to create new passages and uncover buried items, and has improved senses, including the ability to follow scent trails.[i]". Is that enough to answer the question?
Answer: yes
