Essentialy an unsually aggressive Tumble Weed. Indigenous to rural America, the Rumble-bumble-tumble-weed has a larger mass than its Tumble Weed counterpart and is capable of travelling at higher speeds. The kinetic energy produced by the Rumble-bumble-tumble-weed is unprecedented. Small to medium sized farm arnimals are particularly at risk as they become entangled in Rumble-bumble-tumble-weeds complex knottyness.

Sometimes animals are found without their skins, and sometimes much much worse...
