The Mask sneaks into the Hufflepuff common room/Grounded

Another grounded video for that hideous Jim Scary demon, and it's in the Harry Potter universe. The Mask is naturally sorted to Slytherin, but his cartoon abilities allow him to enter the most comfortable and most safest common room of all, Hufflepuff, and uses that opportunity to stalk and terrorize me! Why does an abomination like him have to exist? I want justice, I want justice, I want justice and I want it now!!
