Oysters
Oysters are a collectible in Grand Theft Auto: San Andreas. There's a total of 50 oysters dotted across the state of San Andreas and most of the time require the player to dive underwater while a number of them can be found in pools by hotels or mansions. A quick way to obtain oysters is using a Sea Sparrow. While collecting them, the player's lung capacity improves and makes it easier to collect oysters deeper in the water without losing health or risking death. Collecting all 50 is required for 100% and the reward for this, gives Carl Johnson the ability to date any of the girlfriends available without having to change his physique or clothing. NOTE: IF you accendently kill your girlfriend, she will respawn at the exact same place that you met her. This unfortunatley does not work for Millie, and Denise.
