Honebōn are a sub-species of Fishbone that appear in Super Mario Land 2: 6 Golden Coins. Much like Fishbone and Jean de Fillet, it is said to be the bones of a Cheep Cheep and due to its undead nature it is nearly indestructible. Unlike Fishbone, it appears alone and swims around a small territory, moving in a large upside-down V motion. It usually appears in confined spaces, thus making it difficult to avoid. It can only be defeated using a Star or if Mario is able to strike it with a Koopa Troopa shell.
