The Persimmon (Japanese: カキ) is an item in Densetsu no Starfy 3, found in Old Castle (Stage 10-1). It is not available on the Items List. From a Shell Tape, Starfy, Starly and Moe find out that a special item is required to open the large door to Old Castle and Starly suggests that the item may be a Key. Instead of a Key (Kagi), Starfy finds the similar sounding Persimmon (Kaki) and gives it to Starly but Starly throws it back at Starfy apparently thinking it is no good. On the contrary however, the Persimmon lands in the statue above the large door's mouth and the doors open.
