CookieRun: Kingdom’s second half of the 6.6 update keeps the summer momentum going with a new playable Cookie, the return of fan-favorite events, and fresh cosmetic rewards. Orange Cookie steps onto the court in the RPG with Electricity-type damage and team synergy, while players can dive back into co-op minigames and server-wide delivery challenges. Here’s what to expect in the continuation of the Summer Breeze on Starlight Island patch.

Are there new Cookies in the 6.6 update?

Orange Cookie is the newest Epic to join CookieRun: Kingdom in the 6.6 update. She’s a Magic-type rear-line Cookie who brings a fast-paced, Electricity-based playstyle that thrives when supported by other Citrus Squad members.

Orange Cookie’s strength lies in her ability to amplify damage across the team. The first ball explosion applies Zesty Juice, which increases CRIT DMG taken and inflicts Zap. The second and third balls deal extra damage to already-zapped enemies. On top of that, teammates who land CRITs on Zesty Juice-tagged enemies trigger bonus Electricity damage and further debuffs.

Her passive, Citrus Party, grants scaling CRIT%, CRIT DMG, and Electricity-type damage boosts based on the number of Citrus Squad Cookies in your lineup. With a full squad, she also grants a powerful buff to the Cookie with the highest ATK at the start of battle. All of this makes Orange Cookie a top-tier cookie for burst-focused or Electricity-themed teams, and a standout addition for the summer update.

What’s the Palm Tree Harvest Festival about?

This co-op minigame pits up to 8 players against a giant palm tree in a rhythm-based chopping challenge. Players dodge falling branches, collect T-R-E-E letters to activate Fever Mode, and rack up points through combos. A tougher “Hard Bark” mechanic drops in the second week, giving players a reason to stick around and chase higher scores. Your performance earns Town Square Coins, which can be traded for rewards in the event shop. It’s fast, competitive, and an easy source of event currency.

What’s changed in Error Busters Season 2?

Starlight Island returns as the setting for Error Busters Season 2, a glitchy combat mode with randomized enemy waves and team comps. This time, a new ranked ladder has been added alongside bug-fix mechanics and updated enemy types. Progress from Season 1 carries over, so returning players can build on what they’ve already unlocked. The seasonal shop has also rotated, giving players a new batch of items to farm. If you’re into efficient team-building, this is a great spot to put your squad to the test.

How do Golden Age of Trade and United by Trade work?

CookieRun: Kingdom’s 6.6 update brings back two trade-focused events with different mechanics but shared seasonal rewards. Whether you prefer solo progression or server-wide collaboration, both offer worthwhile rewards with minimal grind.

• Golden Age of Trade: A solo logistics event where you fulfill delivery requests using goods from your kingdom. Completing each trade earns Beach Party-themed items, which you can exchange for rewards.
• United by Trade: A server-wide collaboration event that tracks the total value of cargo delivered by all players. As milestones are reached, rewards unlock for everyone participating.

Golden Age of Trade is ideal for casual players. You don’t need to play constantly; just log in, restock your goods, and complete the available orders. It’s a steady, low-pressure way to stack rewards over time.

On the flip side, United by Trade adds more incentive for high-value deliveries. Players with upgraded production buildings or optimized resource chains can make a real impact. Since rewards scale with server participation, this event encourages coordination across communities and guilds without relying on direct PvP or leaderboard climbing.

Together, these trade events round out the 6.6 update’s offerings with something slower-paced, helping balance out the energy of Error Busters and the Palm Tree Festival.

Are there new Cookie costumes in this update?

Yes, CookieRun: Kingdom 6.6 brings two new Epic costumes tied to the summer “Summer Showers” collection. These outfits are purely cosmetic but arrive with limited-time availability and polished designs worth grabbing if you care about squad aesthetics.

• Caramel Choux Cookie – Promenade in the Rain: A soft, romantic look with muted colors and subtle animations that match her elegant personality.
• Peppermint Cookie – The Frog Prince: A playful, storybook-style costume complete with whimsical details that lean into his fantasy vibe.

These costumes don’t affect gameplay, but they’re visually unique and tied closely to this season’s theme. Like previous costume events, they may be accessible through special banners, gacha pulls, or shop bundles. If you’re a collector or just want to style your lineup for summer, this is the time to roll before they disappear. As always, limited-time cosmetics tend to become harder to obtain later, so don’t assume they’ll stick around for long.

With these additions, Devsisters continues to expand the game’s visual variety without bloating the meta, giving players more ways to personalize their experience without power creep.

The second half of CookieRun: Kingdom’s 6.6 update keeps things fresh with a new Electricity-heavy Cookie, meaningful progression events, and cosmetics that bring style to your squad. Whether you’re optimizing for rewards or just vibing with summer-themed content, there’s plenty to log in for.
