Chocolate Frog Card
Chocolate Frog Cards come tucked inside Chocolate Frogs, each picturing a famous witch or wizard who moves and may wander out of the frame, and Ron has hundreds of them.
Harry opens his first aboard the school train and finds Albus Dumbledore, whose card names him headmaster, credits him with beating Grindelwald, a Dark wizard, in 1945, and adds that he enjoys chamber music and tenpin bowling. When Harry turns it back over the face has gone, and Ron says it will be back. Soon Harry also holds Morgana, Circe, Paracelsus and Merlin, and Ron, who is missing Agrippa and Ptolemy, takes a frog of Harry's in hope of Agrippa.
