Spindel's Lick'O'Rish Spiders are candies. They are shaped like spiders, and may be bewiched to seem alive, like other candies, the Chocolate Frogs.
They were seen mostly on a Deleted Scene of the film, where the students, arriving from Hogsmeade Village, showed the other students what they have bought there. A package of Spindel's Lick'O'Rish Spiders is lying on a table. On the Special Edition of the Prisoner of Azkaban Film, in the extra game Catch the Scabbers!, this candy is seen again on a table of the Great Hall.
