A very violent species of penguin-eating sheep, the Shprogshel (also called "Killer Wool", "Doom Flock", and "Cotton Chaser") spend most of their time hunting down and devouring penguins whole. They are native to the island of Baa, but have been found in the forests of Antartica, though they were removed to Baa. No doubt some over-ethusiastic sheep lovers tried to keep one and study it, but got ripped to shreds when it escaped. They breed like rabbits and a program has been set up to exterminate them. So far, they could only fence them all onto the island.
