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.

Cheese Puffs loves to eat cheese puffs. He rummages through human settlements day and night, hoping to find one of those lovely bags of puffs. His fellow cavemates know that his cheese puff obsession has grown to the point of no return, and thus they make no effort in stopping his cheesy rampages.

Nobody knows what Cheese Puffs' personality is, since he's always looking for cheese puffs and has no time to talk.
