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.

Yummy Yummy Cheddar is fun loving and social. He isn't easily angered, and is a bit stupid. Because of his stupidity, he often doesn't recognize insults. The one thing that makes him angry is trying to be eaten, but even when he is angry, he is relatively harmless. It is true that his gender is unknown, but he likes for people to call him a boy, because he finds being an adult and still not having a gender a bit embarrassing.
