Bottles are items that can be collected in-game through story mode or brawling. You may only start collecting bottles through brawls once you have found at least one of the bottles through story mode. There are 6 types of bottles; Red, Orange, Green, Water, Blue and Violet. Once you have collected all 6, you will be able to claim a pirate. These pirates are categorized as Bottle Pirates. To protect your bottle from being taken by other players, you can place Booby Traps on the bottles. When a booby trap is placed and you lose a brawl, you will not lose your bottle but instead it will use up 1 trap.
