Misty is struggling to feel at home after moving to Maretime Bay. She loves spending time with her friends, but adjusting to life with a newly un-long-lost dad and a newly found freedom is harder than she expected. On her quest to discover as much as she can about her new surroundings, Misty unearths a strange board game: Maretime Mysteries.

It calls to Misty, and she decides playing the game will be the perfect way to connect with her new friends and her new home. But there's more in the dusty box than dice and cards. The board game releases a curse on all of Maretime Bay, sapping energy from the residents and enchanting the town. If Misty and her friends, Sunny, Hitch, and Sparky, can't solve the puzzle of Maretime Mysteries, their home will be cursed forever!
