Walruses were the main security forces employed by Sir Raleigh to protect his boat and his storm machine, the secondary security force being the Squid guards. They could be seen patrolling in most parts of Sir Raleigh's boat. They used a vast arsenal of simple, yet effective weapons to prevent intruders from infiltrating the Welsh Triangle. Their weapons were also used to plunder wrecked ships. All the Walrus guards was arrested, along with Raleigh, and thrown in jail at the end of the episode.
