Onion Cookie/LINE

"What if a ghost appears?..."

- Onion Cookie

Onion Cookie is an S-rank cookie in LINE Cookie Run. She was first released on Halloween in Kakao Cookie Run, and was released on December 21, 2015 in LINE Cookie Run.

Skill
When her green bar fills, she will enter a haunted mansion full of cursed furniture she can run through to get points, as she is all about passing obstacles just like Vampire Cookie.

She also has an additional benefit of being able to pass obstacles under the effects of a Blast Jelly.

Strategy
Onion Cookie is all about passing obstacles and her combi pet, Onion Fish, is perfect for her. She does not emit a mini Magnetic Aura when going through the haunted mansion, but it is not really needed anyway. Using treasures that slows Energy drain like the Supremely Yummy Monster Muffin and Specially made Flaming Cocktail are excellent for her so she can run for very long periods of time.

She is also an excellent candidate for the hard-to-use Sacred Galloping Earring of Wind treasure for scoring purposes if you pair her up with Onion Fish. Another combi you can try is using the Candy Inline Skates with Ghost Butler, as you can double dip on her ability to pass obstacles through potions and blast jellies.

You may want to turn off Cheesecake Cookie and Special Force Cookie's Power+ abilities if you are planning on using her, because they could potentially destroy all the furniture she needs to pass through when they trigger preventing her from getting points.

Trivia

 * She was introduced during the Halloween event in Kakao which does not expire until close to the middle of November without a costume, which could suggest that she was slated to be released after Halloween.
 * She is also the first Cookie released thus far that is very expressive. She has zero happy sprites (which is a stark contract to Cherry Blossom Cookie whose has not even a single angry or sad sprite), although she does show a rare sign of relief when she runs out of Energy.
 * It is speculated why she is almost always teary is because she is wearing a literal onion on her head (or at least the skin). Onions tend to make people tear up from the amino acid sulfoxide that is released when people cut into onions, and since the onion on her head is already cut up, well...
 * When she becomes transparent and runs through obstacles, she freaks out more than usual.
 * She is the fourth Cookie to change the background music while running, after Rockstar Cookie, Mint Choco Cookie, and Peach Cookie, albeit temporarily like Peach Cookie.
 * She is the fifth Cookie to have his or her signature background music while his or her Skill is in use, the first four being the aforementioned Cookies as well as Adventurer Cookie.
