The Black Flan, also known as Pudding, is an enemy from Final Fantasy IV. It is one of the tougher Flan-type enemies found on the Red Moon, having a respectable sum of HP, but it is susceptible to many status effects.
Final Jelly (ファイナルゼリ－, Fainaru Zerī?) appears as an Egg Monster in the Japan-exclusive Hanjuku Hero: Aa, Sekaiyo Hanjukunare...!. The sprite is a modified version of the Flan type of monsters from Final Fantasy IV.
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.
