A Gnome hole is a hole which belongs to a Gnome. Many of these can be found around Hogwarts School of Witchcraft and Wizardry and the grounds. If the students at Hogwarts, especially Harry Potter, come across these holes and some gnomes they will grab the gnome and throw it into the hole which will result in Bertie Bott's Every Flavour Beans being thrown out because of a loud crash in the gnome's home. Also Imps can be thrown in here, however this won't result in Beans as they don't belong in there.
