Mad Scrubs appear as small, plant-like creatures covered in leaves with glowing yellow eyes, and large circular snouts. They possess no arms, but they do have two small legs.
Mad Scrubs will typically shoot Deku Nuts at their opponents. If their foes get too close, they will hide in the giant flower they reside in. They could be easily defeated when Link used his shield to reflect the deku nut projectile thrown at him. This would knock the scrub out of the ground, and then Link could kill it with his sword.
