Which character, from the "Mr. Men" book series, wears a green hat and glasses?

"Mr. Men" series of books have been making parents and children laugh since it was created by author and illustrator Roger Hargreaves in 1971. His first ever character, Mr. Tickle, was born when his son Adam asked what a tickle looked like.

Since then the "Mr. Men" and "Little Miss" books have gone on to sell over 250 million books worldwide with one selling every 2.5 seconds. The first books introduced children to characters kids still recognise and love today, including the blue Mr. Bump wrapped in bandages, the yellow Mr. Happy with his huge smile, the chaotic Mr. Messy and pink Mr. Greedy eating everything in sight.

"Mr. Clever" is the thirty-seventh book in the "Mr. Men" series. It was released on 18th March 1978. He wears a green hat and glasses. He was quite the cleverest person ever. The cleverest person in the world! And, he knew it!
