Herb loved storybooks.
Although he wasn't a very good reader, it didn't matter because he could tell a lot from the pictures. Herb liked the scary ones best with pictures of dinosaurs gobbling up other dinosaurs, or swooping vampires chasing people who had foolishly decided to go for a midnight stroll without any garlic.
Herb read his books everywhere. This was why many of the pages were stickily stuck together, soggy round the edges and usually had bits of banana, biscuit and the odd pea squashed between the pages.
