The phrase references a specific type of creature within the Dungeons and Dragons (D&D) universe, real or imagined. It suggests a small, mammalian predator with an unusual and valuable dietary preference. The reference directly alludes to elements within the game which allow for the design and implementation of original and fantastical creatures, along with associated stats, lore, and behaviors, within a game setting.
Such a concept highlights the flexibility and creative potential of D&D. The implication of such a creature within a campaign could offer interesting opportunities for players. Encounters could involve protecting gold stores, taming the creature, or understanding its unique biological processes. The historical context is within the expansion of monster manuals, where increasingly exotic creatures and abilities have been introduced.
