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.
Typically after being subjected to a violent onslaught victims are usually found dead on the rooftops of buildings up to five miles away.
Sometimes animals are found without their skins, and sometimes much much worse...
I have dead animals on the roof of my house. Why?
Hmm ok... Are the animals intact?
The chickens look fine, the pigs and the cow have no legs and no faces.
Hmm. Was it windy last night?
Twas the Rumble-bumble-tumble-weed!
