The Welding Walruses, also known as Pyro O'Connell, were enemy guards employed by Sir Raleigh to protect the Welsh Triangle from possible intruders. They wear yellow t-shirts and blue overalls. They used welding torches as weapons against Sly. They were also apparently hired to repair cracks of the metallic pipes within Sir Raleigh's boat. If a Welding Walrus successfully lands a hit on Sly, then he will quite literally breath fire and then cover his mouth to burp. They could easily be defeated in one hit. All the Welding Walrus guards were more than likely arrested and thrown in jail, along with Raleigh at the end of the episode.
