This secret student sweetshop was located behind a bookshelf on the Great Foyer, in Hogwarts Castle. In the early 1990s, it was run by a fat Ravenclaw.

In 1991, some "nasty" Slytherins bewitched all the Chocolate Frogs, pumpkins and cauldrons so that they would bounce around. Harry Potter used a Knockback Jinx to stop them, and the Ravenclaw manager rewarded him with a Chocolate Frog Card.[1]
