The Belly Walruses (a.k.a Lil Bowen) were enemy guards employed by Sir Raleigh to protect the Welsh Triangle from possible intruders. While they may be unarmed, they would use their big bellies as a weapon to crush Sly Cooper if they spotted him. They could be easily defeated with one hit. Sly's Binocucom states that they love Sunday Crab Buffets.
- These are the first guards to not use a weapon.
