Metal Scavenger. A shoreline scrapper instinctively seeks metal and gathers it using a magnetic pulse. The creature's accumulated metal forms a portable shelter that acts as its shell.

Hunted for Hoard. A shoreline scrapper's hoard might include more than just rusty debris. As a result of scavenging a shipwreck or sunken city, its metal shell may contain valuables. For this reason, treasure seekers sometimes hunt shoreline scrappers. They hope to uncover riches from the creature's metal-hoard shell, but those foolish enough to engage a shoreline scrapper while equipped with metal rarely survive.

Conditioned for War. Some aquatic and coastal races train shoreline scrappers for combat. On command, shoreline scrappers charge toward enemies and disarm them of metal equipment. Deployed soldiers then enter the fray to annihilate their vulnerable enemies.
