Goggley-Blades are enemies usually encountered by Wario in Wario Land 4. They appear in all Passages except for the Entry Passage. They have pectoral fins like fish but appear to have the hind legs and webbed feet of a bird. They wear goggles and have a blade protruding from their forehead, which they use to try and spear Wario. If they see him, they will swim toward his position with an enormous speed, but if he moves out of the way, they do not change course to pursue him. Goggley-Blades can be defeated at hitting underneath them.
