Perros are docile farm animals seen in Phoenotopia. They greatly resemble chickens, and can be found in many settlements such as Panselo and Atai. Additionally, Adar keeps some in his house, and there is a woman in Daea who owns a Perro but thinks it's a special high-pedigree breed. Being closely related to chickens, Perros can be cooked into meals, and their eggs make for a good delicacy as well.
In Phoenotopia Awakening, Perros play a slightly larger role as they are the subject of various side quests, including one where you must find Perros and bring them to an empty Perro coop back in Panselo.
