Camembert is a sneaky creature, pitter pattering through the night to find new ingrediants for his culinary masterpieces. This often involves stealing, something he's grown very skillful at. No amount of alarms, locks, or angry dogs can stop this rat from finding and taking what it is he needs, possibly due to his more than paranormal existence. He is obsessed with his work and has a large ego, seeing his food as the best there could ever be.
Camembert is also known to be a friend of all rats, and often feeds his tiny four-legged friends the scraps of his projects, causing them to multiply at an astounding speed. When this creature visits a town during his travels, their rodent population grows at unimaginable rates.
