Derek is not a cute sheep. But then you may already know this, if you are a Beano reader, which I’m not.
He’s a crafty sort of sheep, who eats a lot of grass. This is a collection of stories about Derek, by Gary Northfield, presumably previously published in the Beano. What do I know? He’s quite fun. Probably a distant relation of Hälge’s, if elks and sheep can be related. I would guess that in comics they can be.
