"As part of an ongoing battle against invading swarms of giant jellyfish
in local waters, some residents of Fukui prefecture have developed a
method for converting the jellyfish into powder, which is used to make
souvenir cookies. The jellyfish treats, called “Ekura-chan saku-saku
cookies,” are now on sale at JR Fukui station at a price of 580 yen for
a box of 10."
