Scabers are indestructible yet harmless enemies seen in various locations throughout Phoenotopia, especially inside caves. They are spiky, robotic slug-like creatures that slowly move back and forth along floors, walls, or ceilings. They move very slowly and are not hostile but will passively damage Gale on contact. Scabers can't be destroyed, but attacking one will cause it pause for a moment before changing directions. According to Ruth, they're remnants of some sort of ancient technology.
Scabers return in Phoenotopia Awakening with the exact same behavior, but with new graphics that make them look more metallic and well-defined.
