Wallabies are native to Australia and are not the same as Kangaroo’s. Australia produces a lot of the world’s raw material for morphine and related opiates.
In 2009, a lawmaker was quoted telling press “We have a problem with wallabies entering poppy fields, getting as high as a kite and going around in circles, then they crash. We see crop circles in the poppy industry from wallabies that are high.”
Side note, the most famous wallaby has to be Rocko from Rocko’s Modern Life. The characters from the show were based on the personalities of their real life animal counterparts. Rocko was inspired by a wallaby at the zoo that seemed absolutely oblivious to the chaos going on around it.
