Grandad had a postcard delivered yesterday. It was from his friend Professor Blink. He is travelling around the world. He loves exploring and going to interesting places.

His first stop was in Cambodia, in South East Asia, a long way from our mouse hole!
He has been snorkeling in the sea. Look at the fish he saw. I have never been snorkeling.The professor had to wear a special mask and flippers. He had a great time.
