Initially, only its beak/mandible is visible, protruding from the wall, opening and closing. When Trace gets level with it, it launches itself out making a screeching noise. It only moves horizontally, and continues until it reaches another wall, embedding itself into it. If Trace remains on its level, it will continue constantly attacking back and forth.
It has two large, curved mandibles. Its body has spines down its length, and a violet orb/eye in the center. Its tail is almost as long as the rest of it.
Some Scissorbeaks are completely obscured by foreground scenery. They can be detected by a faint intermittent rumbling/crunching noise they emit while stationary.
It can be attacked from above or below while embedded in the wall by shooting at the protruding part.
When corrupted, Scissorbeaks leave a trail of blocks behind. The Cyan Scissorbeak is unique in that it is the only enemy in the game with two different corruption behaviors.
Most Cyan Scissorbeaks will leave a line of drillable/destroyable rock.
However, Cyan Scissorbeaks found in the upper-west portion of Eribu will leave behind a solid neon green trail of destroyable blocks.
The trail these creatures leave can be walked on or grappled to reach certain hard to reach room sectors and items.
