Two types of Halloween season limited menus are on sale from the "dark" soft serve ice cream specialty store "coisof". The sale period is until October 31st. The price is 800 yen each (tax included).
"Pumpkin" is a cute ice cream topped with pumpkin Mont Blanc, which is recommended for lovely people.
"Purple Sweet Potato" is an ice cream topped with purple potato Mont Blanc, which is recommended for mysterious people.
Both of them use rich milk soft serve ice cream, and are served with Halloween-like pumpkins, ghosts, bats and other ornaments as toppings. In addition, there will be a campaign where you can get "Oiri toppings" that make soft serve ice cream even more cute when you post it on SNS with hashtags.
