The Christmas Cookies are a food item which is gotten from a promo code. The promo code was given out as part of the Christmas Countdown during the Christmas 2015 event. The code was active until January 1st, 2016 and gives 10 cookies.
Creatures love these just as much as Santa does, but a creature gets more than happiness - it gains 25 clicks!
Christmas cookies can be fed to creatures. They will increase the total clicks of the creature by 25.
