Baby Camel: Mum, why do we have such a huge hump?
Mum Camel: They’re for storing fat in 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?
