Oh No!: Or How My Science Project Destroyed the World

I've definitely gushed about Dan Santat's illustrations before so I don't need to go into detail except to say that they're still lovely.
This story is about a girl in Japan whose science fair project, a giant killer robot, busts through the wall of her school and started rampaging through the town. “I probably shouldn't have given it a superclaw, or a laser eye, or the power to control dogs' minds.”
Amazing.
