The wave bird looks a little like al (the green bird in angry birds seasons) but with a straight beak and is a metallic teal colour. When tapped, she will shoot to the top of the screen, arc, then shoot to the ground, arc, then shoot back up again. This continues until she leaves The screen. She is only 25 BMUs (bird measuring units) tall, making her the smallest bird and absolutely tiny. She is the only bird that will function properly underwater.
