A Link to the Past
In Kakariko Village, Link is able to enter the house of blue dressed Informant Women that located at the northwest part of village. Inside, Link can found a Cucco underneath one of the pots. Strangely, Link can sprinkle some Magic Powder on that cucco and it will transform into a full blown women that greatly resembles the Informant Women.
This humanoid version of the Cucco explains that it is the Weathercock in the center of village that watches Link harass the Cuccos. Thus, the Weathercock is responsible for sending Cucco's to attack Link if Link harasses a Cucco. She also tells Link that the human shape is uncomfortable for her.
