The Shuriken Walruses (a.k.a. Mr. Shamus) were enemy guards employed by Sir Raleigh to protect the Welsh Triangle from possible intruders. They used their shuriken-like star as weapons against Sly. Unlike most Walrus Guards, they wore a black leather jacket, a red shirt, and blue jeans. When no intruders are seen, they pass the time throwing the star upwards. They could be easily defeated with one hit. All the Shuriken Walrus guards was arrested and thrown in jail, along with Raleigh, at the end of the episode.
