Perrito is a happy-go-lucky, optimistic dog whose goal is to be a therapy dog in the future. He makes the best out of everything, shown by how unfazed he was when talking about his backstory, in which he was thrown off to a river inside a sock and he made the best of it by getting a "free sweater" out of the sock. As Perrito is the only one who can keep the Dark Forest as a pure and safe place due to the lack of selfishness in his heart whenever he is in contact with the map (as the forest becomes a reflection on the heart of whoever last touched the map), he is the only one who is best qualified to carry it throughout their journey. "Oke Doke!"
