Seafang appears in Chrono Trigger DS as a consumable item in the Arena of the Ages. If given to your monster, the monster will use it and use some sort of Water Tech. Like all the other Arena Items, it cannot be used in the main storyline, and is lost if you give your monster another item. You can only get them at the Nu's shop in the Arena, and it costs 200 G each.
