Baby Camel: Mum，why do we have such a huge hump？ Mum Camel:They’re for storing fat out in the desert. Baby Camel: Why do we have hooves，then？ Mum Camel: So our feet don’t sink into the hot sand. Baby Camel: Why do we have these long，fluttery eyelashes？ Mum Camel: To keep the sand out of our eyes in a sandstorm. A moment later... Baby Camel: Right. So why do we have all this stuff if we live in the London Zoo？
