Mystery Bag is a special type of crate filled with many cosmetics, including seasonal cosmetics. By spending 30 Oranges, the player can receive a crate-exclusive cosmetic, or a seasonal cosmetic from a previous event, without needing to wait for a future event for a chance to receive the item. However, the player has a very high chance of just receiving 15 oranges instead of a cosmetic. In addition, the bag's contents are added onto at Fruitbat Factory's discretion, and therefore it does not contain every seasonal cosmetic in the game. Since the end of the Scramble!! for an Xmas Miracle! event, no new cosmetics have been added to the Mystery Bag, other than Sunglasses and the Christmas Outfit color, which have been consistently added to the Mystery Bag for new characters. The bag also does not contain any of the character model replacing, costumes.
Mystery bags have a limited range of contents, as certain unique and noncosmetic items are not added to it. For instance, the bag does not contain boards, costumes, or any unlocks that can be earned from a campaign. If the player has unlocked all items in the Mystery Bag's reward pool, the bag will no longer be purchasable. However, if new items are added to the bag at a later date, it will become available for purchase again.
