List of Combination Bonuses

Below are lists of combination bonuses when certain cookies and pets are paired during the play.

Combination bonuses from main cookie and pet combination will be carried through the cookie relay. For example, Ninja Cookie and Ginger Ghost combination gives 300 points for double jumps. When Pink Choco Cookie as relay double jumps, 300 points still be awarded.

However, combination bonuses from relay cookie and pet combination will not be carried when cookie relay is used. Instead, the original combination bonus from main cookie will be used or no combination bonus will appear when the main cookie and pet combination does not give any bonus.

The lists below covers the original combination bonuses, or "best combi" that appears in the description column of a cookie/pet.

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. The banner has since been removed in the late September 2015 update.
 * Cheesecake Cookie, Adventurer Cookie, Soda Cookie, Ninetails Cookie, Cream Puff Cookie, Cherry Blossom Cookie, Orange Cookie, Lime Cookie, and Peppermint Cookie are the only Cookies, thus far, that only has one combi in the game.
 * If you play a combi where the Cookie has a combi bonus and then switch to a Cookie/Pet combination that doesn't, the Combi Bonus banner does not disappear. This can bring some pretty interesting combinations such as this (Prophet Cookie naturally does not have a combi bonus with Magic Pod). However, this is only visible to you and not anyone else, and if you refresh the rankings page it will disappear.
 * No-combi-bonus.pngnatively, if you play a combi where a Cookie and Pet does not have a combi and then switch to a Combi that does, the banner does not show up (Cream Puff Cookie DOES have a combi with Owlcorn). However, this is only visible to you and not anyone else, and if you refresh the rankings page it will appear.
