During a raid on an enemy ship, Buggy found a treasure map marking the location of a valuable underwater treasure; during the same raid, the crew retrieved a Devil Fruit: Bara Bara no Mi (バラバラの実 Chop-Chop Fruit). Told of the fruit's value, Buggy switched the real fruit with a fake, and then ate the fake in front of the crew so he could sell the fruit, as it was worth a good amount of money.
But, while privately gloating with both the map and the fruit in his possession, Buggy was surprised by Shanks; he hid the fruit in his mouth, and before he could remove it, Shanks surprised him again and he swallowed it - forever losing the ability to swim, and thus also losing his chance to get the treasure underwater.[7]
