Arthur's Absolutely Fun Day! is a mini-game collection based on the characters from the picture books by Marc Brown including Arthur, D.W., Francine, Muffy, Buster and more. The first ten games are accessed by directing Arthur around a map of Elwood City. Arthur earns gold stars by completing them and after sixteen stars he earns a pass to enter the amusement park Wonderworld where five more mini-games become available. The ten starting mini-games are:
Cooking pancakes at Grandma Thora's House. 10 pancakes are required for a star.
Delivering door-to-door newspapers. Arthur must deliver 10 newspapers to get a star.
Diving for treasure. Arthur must collect a certain amount of treasures and then he is given a star.
