Peach Cookie/LINE

Peach Cookie is a Cookie that was released on December 10, 2015.

Skill
After the green bar fills up, the background changes to a bamboo forest, surrounded by bamboo obstacles. Peach Cookie will destroy those obstacles upon collision, gaining a huge amount of points for every obstacle destroyed. While in her ability, she can collect Bamboo Leaf jellies which can be obtained with Magnetic Aura. She will also emit a Mini Magnetic Aura during this phase, and be able to jump many times up to five times.

Strategy
When her green bar fills, the background and obstacles will change into a bamboo forest setting, and she will be able to destroy all obstacles by just simply running or jumping into them. She will, however, only get points for destroying bamboo obstacles. The bamboo obstacles will pop in for her to destroy (the bamboo dummies, even if they look like they could hurt you with their katanas will not actually do so). The more bamboo she destroys during her phase, the more points she will get. It will start at around 250,000 points but will quickly go up from that point.

There is no real deep strategy for using her - you can just load her down with Slower Energy Drain treasures so she can run longer and there is no real need to use treasures that provides Magnetic Aura, but it can be helpful. However, if the faster she runs the more obstacles she can knock away during her ability, so giving her Increased Base Speed treasures will be good too. A great combination of the two would be the Brain Freeze Iced Choco Biscuit.

She can also jump up to five times during her ability, so she might also be a good Cookie on completing achievements requiring players to jump many times. However, just like Ninja Cookie, it is advised to do this with caution, since she might fall into holes.

Her combi with the Panda Dumpling increases XP gain by 20%, so it's a good idea to pair her up with other pets instead that can help her better such as Foxy Bead or Pistachio Firefly as they will sometimes trigger while she is in her bamboo forest phase which will cause her to gain huge amounts of points. Alternatively, you can go for huge endurance runs with the Tea Cup and Coma Inducing Choco Croissants.

You can also use her for XP Farming as well with the Panda Dumpling. Just pair her up with either Bright Cookie or Ginger Claus (the latter is better, as he also provides 20% Coin Bonus which helps as the Panda Dumpling also generates Coins and has slightly more Energy over Bright Cookie). Go with treasures that increases XP gain such as Chocolate Hardcover Workbook, Rose Life Ice Cream, Eye-watering Wasabi Balm or Fatal Double Stick Icicle. If you want, you can even use treasures that gives both XP and Coin Bonus such as Melt-in-your-mouth Cinnamon Rope and Stoic Piece of the Moon.

Trivia

 * In the Kakao version, she was released as a pair along with General Jujube Cookie. In the LINE version, however, she was released alone. This release schedule is very similar to what happened to all the Cookie releases from Carol Cookie to Cocoa Cookie as they were all released within 2 weeks of each other than one month, as she was released just 2 weeks after General Jujube Cookie.
 * Peach Cookie finally breaks the streak of Cookies with an alternative playstyle with the Jump/Slide buttons. The first was Orange Cookie and the last was General Jujube Cookie.
 * She is the second Cookie in the game thus far that can naturally jump more than twice without requiring to land. The first was Ninja Cookie.
 * On the rankings screen and the Original Combination feature if you save a combi with her as the lead she has an alternate pose. She is the first Cookie to do this.
 * Under the effects of a Blast and/or Giant jelly, she will look like she gains points from knocking away obstacles, but she will not actually do so. Only the bamboo that shows up during her ability will give her points.
 * If she runs out of Energy during her ability, she will continue regardless. However, when it expires she will immediately faint.
 * She was introduced without a newsletter regarding her Package Deal.
 * Her design was probably inspired from Nezha (哪吒), a Chinese god from Chinese lore.
 * The weapon she wields is a bo staff. She calls it her "Peachy Bo-Staff", though, according to her ability name.
 * She will be the third Cookie to change the background music while running, after Rockstar Cookie and Mint Choco Cookie, albeit temporarily.
 * She will be the fourth Cookie to have his or her signature background music while his or her Skill is in use, the first three being the aforementioned Cookies as well as Adventurer Cookie.
