Can you read the title in Braille, running up the edge of the book? There's a great picture on the cover: we're looking down on a town street we're about as high up as the roofs and there are some houses with big wooden shutters around the windows. There's a market going on in the street there are big red and white striped awnings covering the stalls, and we can just make out what's for sale fruit and vegetables, mostly. But right up close to us in the rooftops are two of the most peculiar creatures they're bright green, with big eyes, noses the size of potatoes, and two green antennae like spring onions sticking out from the tops of their heads. They're wearing funny caps, too: one looks like a baseball cap with a curved brim, while the other one resembles nothing so much as a flower pot.
