Cookie Detective: The Butter Painting Affair

Cookie Detective: The Butter Painting Affair is a special event in Cookie Run: Ovenbreak. It is the third Cookie Detective event, focusing on Walnut Cookie and Almond Cookie's investigation of a missing masterpiece painting from the Hors d'Oeuvre Museum. Chapter 1 was released on May 28, 2021, coinciding with the release of Butter Pretzel Cookie, while Chapter 2 released on June 18, 2021, coinciding with the release of Almond Cookie.

Overview
Throughout the event, players collect Case Notes in order to interrogate Cookies and collect their testimonies. Case Notes can be found in Breakout, Cookie Trials, and Trophy Race, appearing more often in Trophy Race or while running with Butter Pretzel Cookie in Chapter 1 or Almond Cookie in Chapter 2. Case Notes can also be earned by completing Missions. Once at least 400 non-Mission Case Notes have been collected in one Round, Case Notes will appear less frequently until the start of the next Round.

Players can only interrogate Suspects with one line of questioning per Round. By collecting testimonies, players gain information that help them deduce the identities of the Suspects. Before the end of the Round, players must choose which of the Suspects they want to detain. They may change their decision any number of times before the Round's end, but must wait 10 minutes before they can do so. Players cannot vote for any Cookies that have been previously detained.

At the end of the Round, the Cookie with the most votes by players is detained, and players then see whether the detained Suspect is either Innocent or Guilty. If a Guilty Suspect is successfully detained, the story will continue, and all players will be rewarded 300 Crystals; however, if a suspect is wrongfully accused, "Someone's Thoughts" will hint towards the Guilty Suspect's identity. In Chapter 1, there are 16 Cookies to investigate, with 6 of them being the Culprits; Chapter 2 investigates the remaining 7 Cookies, with 3 of them being the Culprits.

Chapter 1 consists of 8 Rounds, while Chapter 2 consists of 5 Rounds, with each Round lasting for 2 days. At the end of each Chapter, each player is rewarded 200 Rainbow Cubes for each Guilty Suspect they voted for.
