Camembert is a fat French mouse from the 1999 animated Titanic film, The Legend of the Titanic.
Like his name suggests, he's fond of cheese but just about anything edible will do. During the sinking, he forgets his surroundings, and collects all sorts of delicious meals while the Grand Staircase floods, the main protagonist has to set him straight that food isn't everything that matters in life. He later serves as a link for the Marconi Operators to get their distress calls through, because the wires were sabotaged. He gets shocked by electricity, but survives.
