Wallabies on poppies = crop circles

Thank goodness the mystery of crop circles has finally been solved:

Lara Giddings, the attorney general for the island state of Tasmania, said the kangaroo-like marsupials were getting into poppy fields grown for medicine....

"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," Lara Giddings told the hearing.

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