Sonic Cookie, or simply Sonic, is a Special Cookie released in the second part of the Heart of Courage and Passion update. This special Cookie was added to the game as part of a special Devsisters x SEGA collaboration for Sonic the Hedgehog's 30th anniversary. That's why he does not appear in the standard Cookie Gacha and could only be obtained via the crossover event. But you can obtain him as our fanart Cookie Run Sonic Cookie Sticker.
