The Flobberworm is a ten-inch, toothless brown worm which eats vegetation, especially lettuce and cabbage. Each end is identical to the other, each end chews vegetation and from both it exudes mucus which is sometimes used to thicken potions. It moves very little and prefers to live in damp ditches. Flobberworms do not have teeth, therefore making it impossible to suffer a bite from them.
It is one of the few living creatures capable of being Summoned with the Summoning Charm.
