Family Reunion Achievement
To catch this hidden achievement, select the art gallery map and when you see the golden chicken for the first time take it and take it to where the other chickens are, which is in the area where the arcade is, getting there you will have the achievement.
Remember, do not hit the chicken on anyone, otherwise it will disappear and you will have to restart the map, so whenever you hit an enemy drop the chicken on the ground and when you move forward take it back.
