*I* think, and allow me to be as shallow as damp pavement for a moment, that it was entirely for the color (the green is incredibly striking and draws attention to his mouth/face) and the sound an apple makes. NOTHING else makes that noise and it's just .. guh. GUH. For some cracked reason, it's a hot noise. It's crisp and sharp, a lot like Brian, it's to the point and also..? Apples are easy to get and don't go bad all that quickly.
