This has to have been the narmiest scene ever in a Nintendo game. Instead of being blown to smithereens the houses literally just fall over. "Hahahahaha! I, Lysandre, will knock all your houses down!"

Obviously, this reveals a critical truth about the Pokeverse that is as carefully undocumented as the real nature of the Jennies: Houses are also Pokemon. Here, we see that while in general they are able to withstand the normal forces of nature and thus maintain their disguise, they can still be made to faint with sufficient force.
