The Secret Cave is a small, damp cavern located deep within the Forbidden Forest. A fire crab made this cavern its home. On 24 May, 1993, while "following the spiders" under the suggestion of Rubeus Hagrid, Harry Potter and Ronald Weasley had to travel through this cave. However, they found the exit blocked with thick cobwebs, and had to trick the resident fire crab into burning the webs down for them by luring it there with some plants it was attracted to, which they grew with some phials of Fertiliser they found nearby.
