the elephant can attempt to destroy your house as that can very easily happen in real life
I don't know, it sounds quite possible, but it never occurred to me, not to anybody I know. Also, I may be wrong, but it would suprise me to know of any free elephant for thousands of kilometers around my house. Lastly, my house -- and all the houses nearby -- being made of stone, I am far from certain that even an elephant could do much more than damage the external plaster and chip some of the stone blocks.
So, possible? Sure. "Very easily"? hmmm...
