I've been searching for a collection of short stories I read as a kid. I can't say how old I was, but old enough to read because I read them myself, and certainly I read them over seven years ago (I am 18 now). It was a large book, physically, and thick. It contained short stories (I can't say how many or even if they were all by the same author) and loads of illustrations. In fact, the stories were printed on top of full page or even double spread illustrations. More than that, however, and details get shaky. I'm almost positive one was about making soup; there was one short story that was about a race, and the illustration was of a monster wearing a runners vest, shorts and trousers, and he had yellow or orange skin. There was another story I am almost 100% positive was called "Two heads are better than one". Every story was about monsters and I don't think humans were even involved in any way. Anyone got any ideas? I've filed this under Horror because, y'know, monsters, but I can't even be sure the stories were meant to be scary.
I found it!
The specifically named "Monster Stories", 2002, compiled by Andy Charman. Did indeed involve cooking, and a marathon, and has a story called Two heads are worse than one (I was close!)
Wild guess, is it possible that one of those stories would be Forrest J Ackerman's The Mute Question which ends with a punchline of:
"Two heads are better than none"?
