Icy Rocktor

The Icy Rocktor is exactly like other Rocktors; a strange, worm-like creature that wears a "helmet" made of rocks that lives inside cave entrances. A cave that is plugged up by a Rocktor cannot be entered until the creature is defeated. The Icy Rocktor, if approached, will periodically cover its den with its rock helmet and scatter snowballs around by shaking itself. The snowballs will freeze all but Cyan Pikmin, so those are recommended for fighting these enemies. When defeated, the Rocktor's helmet shatters and it falls into the cave below, allowing access.
