The Lighttime Jubilee is also set to return to Hello Kitty Island Adventure – brighter than ever!

Running from December 18 to January 15, players will be able to help Badtz-maru and Chococat gather light bulbs to ignite lights around Friendship Island while the Little Twin Stars celebrate the “Aurora Amicus” Friendship Lights!
