After 4 decades of being trapped in the "Book of Koridai", the giant Mosquitos (which are giant from radiation from Gravity Falls) escape and attack Hyrule. Their first victim is Duke Onkled. He nearly dies, but lives to tell the tale. The same nearly happens to Zelda, but she is saved by Link. The three all attack and kill the Mosquitos, notably King Harkinian using a Dinner Blaster.
