Fee, Fi, Fo, Fum, and Phooey

Fee, Fi, Fo, Fum, and Phooey were five mice who orbited the Moon 75 times on the 1972 Apollo 17 mission. NASA gave them identification numbers A3305, A3326, A3352, A3356, and A3400, and their nicknames were given by the Apollo 17 crew (Eugene Cernan, Harrison Schmitt, and Ronald Evans).
