The Selfish Squirrels are one of two types of rooftop guards in the episode In the Air Tonight in Sly Cooper: Age of Thieves.
Seeing as the Selfish Squirrels are red squirrels, much detail about their fur color and species needn't be delved into too much. But anyway, the Selfish Squirrels wear a pilot's vest and goggles. In one hand, they have a large monkey wrench, and in the the other hand they have a toolbox.
These rooftop guards love getting in close for some close-range combat, which they specialize in. They also have a lot of attack variety.
