Obviously, there's only one breed of sheep that fits the bill:

Angled Saxon (they produce lean meat!) and are inclined (it's getting worse) to invade - travelling by gravy boat (that should keep the juices flowing) to new pastures where the lambast the local populace into submutton to them.

Apparently EH are producing a Dalek that wipes out all alternate theories and hovers over the hill ranting "Excavate! Excavate!"

Sorry: sunstroke!
