Trivia

 * The red banner you see under Cookies and Pets in the Weekly Ranking screen that triggers a Combi Bonus has been changed from Best Combi to Combi Bonus in the 2/6/2015 update. This is likely because some of the additional/hidden Combi Bonuses are better with certain Cookies and Pets than their native Best Combi.
 * Cheesecake Cookie, Adventurer Cookie, Soda Cookie, Ninetails Cookie, Zombie Cookie and Muay Thai Cookie are the only Cookies, thus far, that only has one combi in the game.
