In the forest lives the wild long tailed Guinea Pig. She scampers up tall trees and wraps her powerful tail around a small branch to hang nose down waiting for her pray. When hapless victim wonders by our friend releases her grip rocketing earthward with a screech to make the kill.
In Australia where the opposite direction of the earths rotation has caused, over many millennia, an evolutionary change resulting in the wild long tailed Guinea Pig becoming nearsighted the Army was employed to comb the countryside at arms length to dispatch the creature. Many unfortunate country folk pleasantly strolling the woods had been landed upon, with several deaths.
