A Flesh-Eating Slug is a magical creature very similar to its namesake, the common garden slug. The spittle of the Flesh-Eating Slug has a corrosive effect on both skin and plants. It is a garden pest, and in 1992, the Hogwarts Gamekeeper Rubeus Hagrid explained to Harry Potter that Flesh-Eating Slugs were ruining all of the school cabbages. The only known way to get rid of these slugs is by using a specific repellent that can be bought in Knockturn Alley.
