These intelligent aliens are pink in color and have a serpentine body with razor blades for hands like the Hopping Vampires in China. They wear a blue clear helmet where the massive cranium is and have beaks for mouths, they have blue eyes with owl-like eyebrows. They communicate with alien-noises.
When close, they do a X-Shaped slice with their blades, when near, they shoot a pink energy ball at you, when far or unreachable, they shoot a pink slice of energy that does very good damage. Unlike other rooftop guards, they take 6 hits to defeat.
- The name of these aliens is often said to be Cerebullum, which also means a part of the brain.
