Don Sausser saw this strange site from his vantage point high above Sherman Avenue at 4:30 p.m. Wedneday. In the first photo, a green-costumed character accompanied by a friend shaped like a giant, green eraser walked eat on Sherman Avenue, around Independence Point ending at Bonsai's parking lot. In the second photo, they're crossing 1st Street at the Coeur d'Alene Chamber of Commerce building. Then, the eraser disrobed in the Bonsai parking lot and smashed his costume into a Bonsai Dumpster.

Question: Can you provide a back story for these two characters?
