The Invasion

The Aliens never stood a chance. They made the classic mistake of not realising the speed and sheer fatal damage that a thousand sheep's teeth could do to their army out in the field. Their cries rang out 'Baa I've been bit', 'Fetch the Field Doctor' and 'Ow'.
Finally a strange quietness descended upon the scene (apart from the odd burp or explosion of flatulence) 'The Mothersheep' hovered nearby ready to beam up the survivors but there were none - they hadn't reckoned on the appetite of one of these giant woolybacks.
