== History ==
During the 1993–1994 school year, a time-travelling Hermione Granger threw a shell, resembling that from a snail, into Hagrid's hut, which struck Harry Potter in the back of the head.
In the 1995–1996 school year, snails were used in Transfiguration class as part of the Vanishing Spell curriculum. As an invertebrate, they presented less of a challenge in vanishing than a vertebrate like a mouse, though it was still considered some of the most challenging magic of its type.
