"Professor McGonagall watched them turn a mouse into a snuffbox - points were given for how pretty the snuffbox was, but taken away if it had whiskers."
— The Transfiguration first-year final exam in 1992[src]

Mice to Snuffboxes[4][2] (incantation unknown) was a transforming spell that transfigured mice into snuffboxes.[1] When performed incorrectly, the snuffbox might grow whiskers.[1] This spell was taught in first[1] and third-year[2] Transfiguration classes at Hogwarts School of Witchcraft and Wizardry.

During the 1986–1987 school year at Hogwarts, Professor Minerva McGonagall taught third-years how to perform this spell in Transfiguration class.[2]

During the 1988–1989 school year, Professor McGonagall once again taught third-years this Transfiguration spell, and a few mice managed to get loose. Jacob's sibling and Jae Kim helped her find them and tidy up the classroom.[5]

During the 1991–1992 school year, this spell was taught to first-years in Transfiguration class, and the practical end-of-year exam concerned the correct casting of this spell.[1]

Behind the scenes

  • In Harry Potter: Hogwarts Mystery, the wand movements for this spell and Vera Verto are identical in their Transfiguration lessons, however, the game files identify only the movement for this spell to be correct, whereas the movement for the latter is in fact an entirely different movement.
