In a nook on the right-hand side of the basement corridor stands a large stack of barrels. To most students, such a sight might seem unimportant. However, to those who were sorted into Hufflepuff, these barrels are invaluable. Concealed behind one of these barrels is the entrance to their common room, which has not been seen by a student belonging to another house in over a thousand years.

Of course, anyone is welcome to attempt accessing the sanctum of Helga Hufflepuff. You only need to tap the barrel two from the bottom, in the middle of the second row, in the rhythm of 'Helga Hufflepuff.' Any member of the loyal lady's house will be able to do this with their eyes closed and get the lid to swing open and expose a crawl-way, but anyone else will find themselves in a sticky situation. If the wrong lid is tapped or the rhythm done incorrectly, you will instantly be doused with vinegar and barred from accessing the common room. With that said, tap carefully.
