A small fictional object often referred to as a day to day nuisance. A single Smurn is approximately the size of a corn flake, but they only ever found in large quantities. They are possibly living organisms, and capable of extremely speedy reproduction. An efficient way of treating a smurn infestation is yet to be determined.
