In Tasmania the legal production of poppies is a major industry. According to the BBC they provide about 50% of the worlds legal opium “for morphine and other painkillers.” Some of the local Wallaby population has taken to digesting the plant and then wandering through the fields high. This wandering is producing “crop circles.” Those worn down designs and mazes visible from the sky, believed by some to be the work of other-worldly beings, but not is Tasmania–It’s the Wallabies.
(Rumor has it they are not all exactly indigenous so this would still technically make them ‘aliens’ crop circles.)
Several thoughts come to mind if this were happening in America.
