Shock-o-Choc is one of the candies sold by Honeydukes Sweetshop in Hogsmeade. They are made of chocolate, and are sold on packages weighing approximately one-hundred and seventy grammes. In early-1996 Colin Creevey, with the aid of Harry Potter, sent boxes of these chocolates filled with Howlers saying "really rude things" to the Inquisitorial Squad.
