When I saw set 75936 first time I fell in love with this huge T. rex. Then during building it I found big similarity between body of T. rex and chicken I had for lunch. This gave me initial idea: "Is it possible to rebuild T. rex into chicken and use only its parts?" Now I can say YES! I used original legs, modified body, make neck longer, built new tail, wings and head and here is Chicken rex (in short C. rex). It feaures moving legs, wings, neck, head and opening beak. You can find its detailed review here. And by the way it is even life-size - you can see my chicken besides medium sized egg for comparison at picture bellow.
