Ticking Treasure Chest

Ticking Treasure Chest (Korean: 다이너마이트 보물상자, daineomaiteu bomulsangja, "Dynamite Treasure Chest") is an Epic Treasure released alongside Macaron Cookie during the Wicked Breakout Party update. It summons a chest that contains various Power Jellies, which are cycled in a rotational manner.

Story
''It might look like a chest full of explosives, but no worries: there are only treasures inside. Though, we would recommend you to take cover when it explodes!''

Trivia

 * Ticking Treasure Chest, Coin Fireworks Box, Rainbow Bear Roll Cake, Fiery Candy Comet, Divine Aurora Extract Flask, and Bubble Gum Spring Jumpers were the first six Epic Treasures for Cookie Run: OvenBreak, all debuting within the same update.
 * Ticking Treasure Chest had a bug where it'd spawn two chests in quick succession if the Cookie is blasting fast enough during its skill activation, which resulted in abnormal gameplay. This was later fixed during The Living Deep Sea City update.
 * Rarely, Ticking Treasure Chest might spawn in an area with no floor, resulting in it de-spawning shortly after. Making it so the player loses a Power Jelly item.
 * It is unclear if this is supposed to be an intended game mechanic or a gameplay bug, since this feature continues to exist years after Ticking Treasure Chest's release.
 * This Treasure appears in a cutscene for the The Treasure and the Crow story.
