Opium Eating Alien Wallabees and their Sinister Artifacts

From Boing Boing:

"The one interesting bit that I found recently in one of my briefs on the poppy industry was that we have a problem with wallabies entering poppy fields, getting as high as a kite and going around in circles," (Tasmania attorney general) Lara Giddings told the hearing (on poppy crop security).

"Then they crash," she added. "We see crop circles in the poppy industry from wallabies that are high."
