The plot could be that a family receives a box of smelly cheese as an anonymous Christmas gift. They try to figure out who sent it while also dealing with the smell. Eventually, they find out it was from an old friend who remembered how much they loved strong - smelling cheeses as a joke.
Maybe there's a smelly cheese that has the power to make Christmas wishes come true. A group of kids find this cheese in an old attic on Christmas Eve. But they have to endure the smell while they make their wishes. One by one, their wishes start coming true in the most unexpected ways, like the snowman coming to life or the Christmas tree growing to the ceiling.
