If you could talk to the animals.

At some of the animal observation windows at the zoo, the animal sound is broadcast over a loudspeaker.  Clara and Miles and I were at the zoo and heard the growling polar bears, roaring lions, and snorting/grunting hippos.   Miles was intently observing the two hippos in the water, while their recorded snufflesnorts filled the air.  He turned and looked very seriously at me, eye to eye, and said,  emphatically,  in his baby voice, "Hippo say, 'Let it go.  Slam the door.'"
