Crouch is an small trilobite-like Bydo that travels in small or large hunting packs, gliding (or swimming) swiftly across environments where Bydo biology runs rampant. They constantly spew out Bydo Shots as they pass by intruders entering their territory, but they can still get killed very easily. They are only encountered in Evil. There was originally going to be another variant of this enemy, albeit with different attack patterns as well as a different color scheme, but it has been removed from the final game for unknown reasons.
