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.

Z'No Place Like Home came to Lagie's caves from another esteemed cavern, and prior to that her egg was found rolling about in the jungle. Z'No Place Like Home has always been uncertain about where her favourite home is. She's happy where she is now, but she's sure she had good times before. "The problem with having lived in many different places," she says, "is that when you're homesick, you don't know where you're homesick for." The only thing that Z'No Place Like Home is sure about is that her favourite place is far away from hungry dragons (they always seem to want to eat her), blazing fires (melting is not the best way to spend a day), and cheese slicers (the stuff of nightmares!).
