Kumiho Cookie is an S-grade cookie. It is sometimes referred in game as Fox Cookie (because the original appearance of this cookie was a fox). This cookie has an ability for creating more points with all bear jellies while in the cookie form. Unfortunately, when players start the game, the cookie will run with the fox form, so players have to make 9 double jumps before it will evolve into the cookie form.
Originally a fox-shaped marshmallow. She aspired to be a cookie so much that she survived on only flour and butter for 900 days while mastering the sorcery to fake a Cookie. As a result, she can now disguise herself as a seducing and appealing cookie. Anyone who catches even a glimpse of her will fall in love with her.
Ninetails Cookie starts her run in her fox form. Try to reach nine double jumps as soon as possible to turn into her Cookie form- DFJ (double finger jumps) decrease the time needed to double jump and are the best to use. While she is in her Cookie form, try not to use any double jumps unless absolutely necessary to keep her jump count low because after 9 double jumps in cookie form, she will return to her fox form. Entering Bonus Time in Cookie form is ideal, so all bear jellies will become seduced jellies and give her bonus points.
Her combination pet, Foxy Bead, will allow Ninetales Cookie to essentially run over holes and through obstacles to keep her jump count low. What's more, while she's in her giant form she gains even more points due to the combination ability so be sure to nab any Giant Beads and Giant Blast Beads (bestowed by Foxy Bead) along the way.
Ninetales Cookie was based of a Korean mythology, the kumiho. The ability that Ninetales has is to 'attract' the Bear Jellies for her to eat when she is in her cookie form. This detail is in common when the kumiho transforms from her fox form to her human to attract the male subject in conclusion to eat his heart or liver. The kumiho can also be known as a nine-tailed fox, hence her name.
It was entirely possible to reach the final stage of Escape from the Oven with just 7 double jumps. If players are willing to collide into obstacles to avoid double jumping, it can be even less. This is optimal if players want to get the best benefit out of Ninetales. However, after the City of Wizards update this is no longer possible.
Ninetales Cookie is the second Cookie so far that uses a double jump system. The first was Skating Queen Cookie.
Ninetales Cookie was an limited-time cookie in the Kakao version. It was unobtainable afterwards. In LINE, players are able to buy Ninetales Cookie like other cookies. This explains why Ninetales Cookie is not in the photo in the Photo Challenge in July 2015, as the photos are already featured in the Kakao version.
In her normal attire, she has one tail in both forms. In her Halloween costume, however, she has nine.
After the update of 27 November 2015, her image in the Cookie Shop showed her dressed in an alternate hanbok, which she is supposed to only wear in the Kakao Version of Cookie Run to celebrate the Mid-Autumn Festival, Chuseok or 추석. However the hiccup was fixed on the next day.
