http://www.petitionspot.com/petitions/birthdaycakeshake/ Anyone who has indulged in the wonderful confection known as the birthday cake shake will know how missed this delicacy is. We realize that it was created specifically for Sonic's 50th Anniversary -- but honestly, it can't be kept away from us forever! Tell Sonic to bring back the birthday cake shake now!
