++ Hufflepuff House

Hufflepuff, founded by Helga Hufflepuff, values hard work, loyalty, tolerance, and fair play above all else. Its animal is the badger, and canary yellow and black are its colors. The Fat Friar is its ghost. According to Rowling, Hufflepuff corresponds roughly to the element of earth.

The Hufflepuff dormitories and common room are located somewhere in the basement (corresponding to earth). To reach it, you enter a door to the right of the main staircase in the Entrance Hall and down a staircase there (GF17). Although it is therefore at dungeon level, it is "as dissimilar as possible" from the Potions classroom.

Their entrance found through a still-life painting that is somewhere near the kitchens. You must give a password to the painting to enter. The Hufflepuff common room is filled with yellow hangings and fat armchairs and it has little underground tunnels leading to the dormitories, all of which have perfectly round doors, like barrel tops (very much like a badger sett). Very few Hufflepuff members are specifically mentioned, and, in general, they are not seen much in the Harry Potter books.

The Head of Hufflepuff House is Pomona Sprout.
