Eternal Wish Meteor

Eternal Wish Meteor (Korean: 끝없는 소원의 유성우, kkeudomneun sowone yusongu, "Meteor Shower of Endless Wishes") is a Legendary Treasure that was released alongside in the second half of the Together at Wish Camp! update. After the player has collected enough Jellies for the initial summoning, an aurora appears, illuminating the top half of the screen, which in turn makes small meteor showers fall. After a certain period of the meteor shower, a gigantic meteor appears, which creates a Meteor Shower Crystal Jelly. The Treasure then spawns a small handful of meteor showers depending on the number of Jellies the Cookie has collected throughout the run.

It can be obtained by purchasing it in the Gem Exchange Center.

Story
Perhaps it's an endless meteor shower to grant all the wishes of countless Cookies.

Trivia

 * Eternal Wish Meteor appears in the Together at Wish Camp! story, as the meteor shower that S'more Cookie saw in his younger days, and wishes to see again.
 * According to S'more Cookie himself, the meteor shower only appears once every seven years. This number corresponds to the 7th Anniversary of Cookie Run: OvenBreak.
 * Eternal Wish Meteor is the only Legendary Treasure thus far to have a flexible Cooldown, as it depends on the amount of Jellies the player has collected throughout the run.
 * Eternal Wish Meteor is the second Legendary Treasure released in a row to not have a Combi Bonus with a Cookie, following lamp of endless dreams.
 * This makes it currently one of the only three Treasures in the game without a Combi Bonus to any Cookie, alongside Lamp of Endless Dreams and carrot pudding trampoline.
 * Eternal Wish Meteor behaves quite similarly to apple candy balloon, albeit without the bonus for all Jellies.
 * Eternal Wish Meteor's internal number is "tr0233".
