Japan has quite a few regional delicacies — Tokyo Banana, for example — and it's traditional to buy beautifully-wrapped boxes of these tasty treats to take home to family and friends as souvenirs.

In Fukuoka, one of these delicacies is Niwaka Senpei, a thin, crunchy biscuit with eyes on it and a little slit for your nose, so you can wear it as a mask — it's based on the Hakata Niwaka masks from Japanese comedic plays.

The biscuit is 115 years old (well, the company is; the biscuits are presumably freshly-made) and in that time, they've collaborated with Hello Kitty, Rilakkuma, and Doraemon, but their newest collaboration with Square Enix is the first time that they've actually changed the shape of the biscuit itself.

The biscuits, in the shape of Dragon Quest's iconic slimes, will be sold in a beautiful slime-themed commemorative box, containing three crackers for ¥756 (£5 / $7).

The tasty slimes are part of Square Enix's promotion for "Dragon Quest Walk", a Japan-only AR mobile game in the vein of Pokémon GO, which has been downloaded five million times across Android and iOS since its 2019 release.

It will be available only at three shops in Fukuoka from the 18th of June to the 30th of September, but you can also buy them online if you don't mind exorbitant import costs for the sake of having some cute biccies.
