The Snow Flan is an enemy from Final Fantasy X found in around Moonflow appearing with other fiends. Guado Guardians can also summon Snow Flans during the escape from the Macalania Temple at Lake Macalania. It will cast Blizzard at a single party member on each of its turns. As with other Flan, it has extremely high physical Defense but can be easily defeated by casting a spell of the opposing element, in this case Fire. Additionally, a Piercing weapon with Firestrike will also defeat it very quickly.
Snow Flan will drop armor with Ice Ward or Iceproof with an empty slot or two. It will also drop weapons with Icestrike and possibly Piercing. In the INT/PAL version, it will also drop weapons with the Distill Mana ability.
Flan is an open pastry or sponge cake containing a sweet or savory filling. A typical flan of this sort is round, with shortcrust pastry, usually coated with sweet syrup. It is similar to a custard tart or a South African melktert.
