Seaberuses are large seahorse-like creatures with the heads of dogs. One head is gray, has floppy ears and has lines on its fur. The middle head is a tarnished yellow and has spots, and the third head is black with dark brown lighting bolts. The main body of a seahorse is dark gray and has markings from all three heads.
Like the Caseusidile, it is highly aggressive and territorial, but it is also devious and stealthy. If one was to enrage a seaberus they would be dragged down to its underwater lair never to be seen again.
