The Onyx Hook is a key item in EarthBound Beginnings. It is one of the only key items that are optional. It is found by fighting The Fish in Magicant's Crystal Cavern where it can be found after defeating it. Its one and only use is to function as a teleporter warping the player back to Magicant. It can be used anywhere, including indoor areas. However, in order to return back to the normal world, Teleportation must be used to similarly warp. Until it is learned, Ninten must trek through the Crystal Cavern and exit via a nearby XX shell spire.
It cannot be used in battle, and in some events such as when EVE is in the party it cannot be used outside of battle. Once all 8 melodies are learned and Magicant disappears, the Onyx Hook loses its ability to warp, rendering it useless.
