Stoner wallabies summon aliens

Firstly - I apologise for yet another animal post.

Poppy fields in Tasmania, Australia, were getting a strange reputation, due to the frequent appearance of crop circles. But the mystery appears to have been solved. Wallabies, hiding their addicted lifestyles beneath a cute and fuzzy exterior, have been breaking into the poppy fields, eating the heads of the poppies, and getting high. They then hop around in dazed circles, crushing the plants and making "crop circles." http://www.news.com.au/story/0,27574,25686924-5000540,00.html
Or at least, that's what a government report wants you to believe.
Perhaps the wallabies are communing with alien masters, who order them to mark out landing sites for them. That's right, when the aliens invade, only wallabies, their willing accomplices, will escape the slaughter!
