"When Grandpa wasn't a grandpa and was just instead a small-fry, hobbledhoy boy blowing out thirteen dripping candles on a lopsided cake, his savvy hit him hard and sudden-- just like it did to Fish that day of the backyard birthday party and the hurricane-- and the entire state of Idaho got made. At least, that's the way Grandpa Bomba always told the story."
Grandpa Bomba's savvy gives him the power to move mountains and manipulate the land. He created the state of Kansaska-Nebransas for his family.
