Mickey (or Minnie) is transported to a magical kingdom called Beanwick, where earthquakes constantly occur. While reading a book of fairy tales before bed, he starts wondering what it would be like to live in this enchanted land. As he drifts off to sleep, he finds himself in the midst of these troubles and decides to offer his assistance.
Mickey's Ultimate Challenge is a puzzle game where players can choose between Mickey or Minnie to play through. The game takes place in the Disney universe and features five characters from this world. Players will be presented with various tasks, each requiring them to solve a different puzzle.
The puzzles vary in type, such as memory games like Daisy's task of cleaning paintings on a wall. After completing these challenges, players receive gifts as rewards.
Upon finishing all the tasks, Mickey or Minnie must trade their gifts with the correct characters. This involves guessing which character would be most pleased to receive a particular item, such as Goofy's hammer. By correctly distributing the items, players unlock access to the final puzzle and character.
