Two major bestselling and award-winning picture book creators combine forces in this kid's eye account of a science fair gone horribly and hilariously awry! Some kids are too smart for their own good...and maybe for everybody else's good. When an overly ambitious little girl builds a humongous robot for her science fair, she fully expects to win first place. What she doesn't expect is the chaos that follows! "I probably shouldn't have given it a superclaw, or a laser eye, or the power to control dogs' minds," she laments. Kids, don't try this at home! "A must-have." --Kirkus Reviews Don't miss the sequel, Oh No! Not Again!: (Or How I Built a Time Machine to Save History)
