Stoned wallabies, high after snacking on local opium plants, are responsible for carving outon Australia's southern island state of Tasmania.
OK, we had the same "say what?" reaction upon first hearing about this story. But Lara Giddings, Tasmania's attorney general, recently told a parliamentary hearing on security for poppy crops that the animals get "as high as a kite after munching on the plants before trying their artistic touch with the local terrain.
"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," Giddings told the hearing, according to the BBC News.
And then they do what any self-respecting wallaby would do in such a state: They crash.
"We see crop circles in the poppy industry from wallabies that are high," Giddings said.
OK sure. But who got the wallabies stoned? Aliens, that's who.
