I felt like Crusher would be a good pick for B1, considering how punchy it sounds. I also added some suggestion notes around the project, mostly with the "Dubiously Infamous BUT HEY, THAT'S JUST A THEORY, A pixelbox THEORY!!!!!" stuff. (Note: I made B1 crusher before I realized that B2 already has a crusher reference)
