Knish Kringle is a cross of Santa Clause and some kind of blue worm. He comes down a chimney and if the Shminger Bread House(a life size ginger-bread house)you made tastes good, he'll put a weird fog around it, eat it, and leave gifts under the debris. If he doesn't like it, he'll go into an unstoppable rage and destroy the house. Gazpacho was dressed as him and Chowder thought it was the real Knish Kringle.
