Old MacDonald's Jungle?

One of Connor's very favorite songs these days is Old MacDonald. We sing it together several times a day. Kirk and I start the lyrics and when we get to "and on that farm he had a ____" Connor calls out the animal on the farm she wants to hear. We never knew that Farmer MacDonald had elephants, lions, and giraffes on his farm, but apparently according to Connor he does. Kirk and I have had fun figuring out sounds for elephants and giraffes to make!
