Halloween Activity Books

Oh goodie, goodie, goodie! Halloween is not as big in this country as it is in mine, but at times, the English make an effort. So I was walking in one of the local shops yesterday when I saw these Halloween activity books. I didn't buy them, although I was very tempted. I think Wolfie might already be a tad old for it, but I might try to convince him all the same. I love doing activity books with him. And, I know you cannot judge a book by its cover, even a children book, but I'd buy them for the cover all the same. What do you think?
