Chest Monster/Literature

Examples of s in include:


 * In Dougal Dixon's After Man, the oakleaf toad is this trope for smaller invertebrate-eating animals. Camouflaged by the leaf-like appearance of its body, it lures in prey such as shrews or small birds with its tongue, which resembles an earthworm.
 * While not an enemy of the protagonist, the Luggage from the Discworld novels is still a ravenous chest monster. But it does its master's laundry. It is, however, quite harmful to everyone else. It can also be distinguished from, say, the sort of luggage to steal underwear from, by the feet underneath. And the fact that it will, without eyes, look at you in a very unfriendly manner.
 * It is, in fact, made of Sapient Pearwood and the inside is much, much bigger than the outside. It's also fiercely protective of its owner, as many a poor schmuck finds out, and will follow him anywhere in time or space, including the most grisly and esoteric of Eldritch Locations. Don't mess with the Luggage.
 * Not just anywhere in time and space. Just plain anywhere, including another universe in which magic doesn't exist or function.
 * The Luggage will literally follow you to Hell and back. And inside your own mind.
