Adopt an Oyster

We all know everyone's dream pet is an oyster reef, or a group of oysters. Who wouldn't want one? If you got an oyster it would clean lots of water. In fact one of the reasons that the Hudson River is dirty is because most of the oysters were killed. You shouldn't adopt an oyster for a pet (because everyone knows cats are the best) however you should promote oyster reproduction by not eating them too much.
