Tub test tube baby is about the twenty-ninth most common naturally-occurring oscillator in Achim Flammenkamp's census, being less common than the tumbler and more common than trans-beacon on dock.[1] It is the 29th most common oscillator on Adam P. Goucher's Catagolue. There are about four regular test tube babies for every three tub test tube babies.
