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.

OxygenJive lives in the cellar, having made a nest for itself out of bits of plaster gnawed from the walls.  It only ventures up from the cellar every so often when it sees mice and other creatures that see it as a giant walking snack.  It will follow around the first person it sees without fail, and only stops when mousetraps are set up around its nest.  It will often leave found buttons or small trinkets at the cellar door as thanks.
