Flumph
The flumph is a monster found in the fictional world of the Dungeons & Dragons fantasy roleplaying game. Flumphs are described as sentient, and are the only Lawful Good creatures in the original 1981 Fiend Folio. For the 3rd and 4th editions of D&D, license-holders Wizards of the Coast primarily used flumphs for comedic value.
