Crazy, Mixed Up Animal Sounds

Audrey thinks all animals make one of 2 sounds - a quack like my Donald Duck impression, or a roar/growl of some kind. So earlier today Eliza and I were trying to teach her animal sounds while playing with her Little People Noah's Ark toy. Audrey has the lions down no problem, but all the rest of the animals sounded the same. So I picked up one of the elephants and tried to make an elephant sound. Unfortunately, I failed miserably. Eliza laughed right at me and said I sounded like a horse! Apparently I can't make an elephant sound, so we moved on.
