Cheese Dragons are not actually alive. They are enchanted items of food that act almost identically to dragons. They have no need to eat, but they must “live” in humid environments or they will dry out and harden.
Quadrello di Bufala is named after the cheese he was created from, one of the most popular cheeses in his homeland. He is a rather fatty cheese dragon, though he has a rather smooth and creamy surface. Quadrello di Bufala is a rather peaceful "dragon", quite content to let other dragons in his cave have a small nibble of rich, robustly pungent body once in a while. Eventually, he will be eaten away to nothing, but until then, Quadrello di Bufala will continue flying around contentedly in his underground cave among other, less animated, cheeses.
