Scabers are indestructible yet harmless enemies seen in various locations throughout Phoenotopia. They're basically spiky, robotic slug-like creatures that slowly move back and forth along floors or walls. They move very slowly and don't do anything to hurt the player; the only way a Scaber can hurt you is if you run into it. Scabers can't be destroyed, but attacking one will cause it to change 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.
