Wallaby crop circles

According to the BBC, wallabies getting stoned on poppies and making crop circles.

This is more of a breakthrough than you might think. We not only have opium poppies growing wild in Britain, owing to some local councils who didn't read the seed packets properly, but there are also wallabies living on the Yorkshire Moors. They're good fun. You can always tell a dog who'd come across one because even very large bunnies tend not to punch one in the nose and it's always worth a laugh down the pub to look mystified while some rambler from down south tries to reveal that he thought he saw a kangaroo that afternoon.

Then we find out they're responsible for all that mashed-down corn as well. Now all we need to do is find out if wallabies were around during the Bronze Age and we'll have Stonehenge sorted out as well.
