One like this won't take up much space and does not require feeding!
One fascinating fact I found out recently is that an adult elephant is capable of eating 200kg of food in one day. They can also weigh up to 9 tons! You certainly wouldn't want one sitting on your desk...
Except this one maybe?
He's a wee baby African elephant painted on a stone collected by me on a walk along the beach. As soon as I saw it I knew what it had to be!
