"What d'you mean, 'we all hate Hagrid'? What's this rubbish about him getting a bad bite off a flobberworm? They haven't even got teeth!"
Harry Potter to Draco Malfoy about Rita Skeeter's exaggerated claims in the Daily Prophet[src]

The Flobberworm was a herbivorous, ten-inch, toothless brown magical worm which ate mainly lettuce and cabbage.[2][4]


An uninteresting Flobberworm

It was not considered a particularly interesting creature, with a Ministry of Magic Classification of X, or "boring", which was the lowest possible rank.[2]

Each end was identical to the other, from which they chewed vegetation and exude mucus, which was sometimes used to thicken potions.[7] It moved very little and preferred to live in damp ditches.[2]

Contrary to the claims of Draco Malfoy and his gang, which were designed to attack Hagrid and his quality as a professor (although he was doing a pretty good job of that himself), Flobberworms did not possess teeth and thus did not bite.[5]

Flobberworms were apparently edible and Flobberworm fritters were sometimes served for lunch at Hogwarts School of Witchcraft and Wizardry, much to the dismay of the student body.[8] Flobberworms could be also be transfigured into fritters with a spell.[9]

The Flobberworm was notable for being one of the few living creatures capable of being summoned with the Summoning Charm, although it was generally not considered worth summoning.[10]


"Nobody really liked Care of Magical Creatures, which, after the action-packed first class, had become extremely dull. Hagrid seemed to have lost his confidence. They were now spending lesson after lesson learning how to look after flobberworms, which had to be some of the most boring creatures in existence. 'Why would anyone bother looking after them?' said Ron, after yet another hour of poking shredded lettuce down the flobberworms' throats."
— Ron gripes about looking after the Flobberworms[src]

The Flobberworm

When he taught Care of Magical Creatures, Silvanus Kettleburn normally covered them in third-year classes. However, as in the 1986–1987 school year, Severus Snape needed them for Potions, students who started learning the subject in 1986 did not get them covered in the class until their fifth year.[1]

A live Flobberworm

After losing his nerve during the Hippogriff debacle in his first Care of Magical Creatures lesson during the 1993–1994 school year, Rubeus Hagrid had his third-year students raise Flobberworms for a term. The exercise was completely pointless, as they prefer to be left alone and to do nothing. They didn't require much care, although they seemed unable to control how much food they needed as they would die if overfed.[4] Later on in the school year, the Flobberworms died from overeating lettuce.[3] At the third year exam in Care of Magical Creatures, Hagrid provided a fresh tub of Flobberworms for the class, and had them keep their Flobberworms alive for one hour, in order to pass the exam.[11]

In the 1996–1997 school year, Snape's first detention of the year for Harry Potter involved sorting out rotten Flobberworms from fresh ones, to be used in Potions, with him requesting Harry need not bring protective gloves.[12]

During the Calamity in the 2010s, several Foundable Flobberworms could be found trapped in large magical green bubble Confoundables. Volunteer members of the Statute of Secrecy Task Force had to release these Flobberworms from containment using the Severing Charm to return the Flobberworm Foundables to their original place.[13]

Usage in potions

"The mucus from the Flobberworm is sometimes used to thicken potions."
— Description[src]

Flobberworm Mucus was a green and slimy substance commonly used as a thickener in many potions. A popular and useful ingredient, it was used in potions such as the Wiggenweld Potion, Herbicide Potion, and the Sleeping Draught.[6]


To flobber means "to sag and wobble".
