September 2012 saw the movement to center stage of Grün as the character I created in cake and icing for Nathan’s Birthday. The character was, and still is, an original. Nathan took to drawing box shapes (squares, rectangles) and then adding faces to the boxes.
Grün got his name from the German word for green, since he had green eyes. This is one of the earlier evidences of Nathan’s predilection for the German language as his foreign language to learn in high school.
