I believe this video is either a hoax or a learned behavior of the elephants. If you look at other videos from this same location in Thailand, you will see other elephants painting the same images.
Tourist attraction? Hoax? Animal abuse?
ANyone ever see the painting that the elephant did at the Dallas zoo for Howard? see the link.
Or the difference Jenny at the Dallas Zoo is an African elephant, while the ones at the Thai Zoo are Indian Elephants. (It's in the ears)
