SukuSuku Inufuku (which means "quickly, lucky dog") features the rather odd-looking dog Inufuku, who also has cameos in some of the later Sonic Wings games. The game spans a year; in January, the player adopts an Inufuku to raise. Throughout the year, the player encounters a variety of characters who challenge her/him to quizzes and competitive games. The player's performance on the challenges influences how her/his Inufuku looks as it grows up. The characters, locations, and title cards for each month that show up in the game also vary.
