Mrs. Norris is Argus Filch's pet cat. Mrs. Norris appears in 3862 Harry Potter Hogwarts, where she had no printing, LEGO Harry Potter: Years 1-4, and 4842 Hogwarts Castle. Although the preliminary figure for this set did not have it, the final Mrs. Norris figure has printing for her face and eyes.
In Harry Potter's second year, Mrs. Norris was petrified (she was not killed since she saw the Basilisk's reflection in the water), along with Penelope Clearwater, Colin Creevey, Justin Finch-Fletchley, and Hermione Granger. Harry is convinced that she can see through invisibility cloaks just like Professor Moody.
- In the movie, Mrs. Norris was not ginger, but various shades of grey/brown.
- She first appeared in the game 3862 Harry Potter Hogwarts. Here, she looks more like she did in the movies. She is dark brown with no printing. In 4842 Hogwarts Castle, she is the same orangeish colour as the hair of Molly, Arthur, Ron, and the rest of the Weasley family. This combined with her new printing makes her look more like Crookshanks, so she can therefore be used for that purpose.
