A little frog with your salad, ma'am? Australian carrier Quantas said Tuesday it has changed its lettuce supplier after a passenger on a flight from Melbourne to Wellington found a live frog in her greens. The one-inch Australian whistling tree frog didn't get a chance to hop away. The woman put the lid back on her meal, preventing any escape. The Quantas plane's crew notified the Quarantine Service while the plane was still in the air and officials were waiting when it landed at Wellington Airport.
