How do I wake up the Snorlax that's in Pokemon village?

I went to the Snorlax in Pokemon village and I've been told that there's a hidden door under the Snorlax and I've been wondering how do you wake up that Snorlax


Best I can tell that snorlax is merely for decoration. Only the Snorlax on the road with the daycare can be woken and caught. Others have reported no success in doing anything with the snorlax.
