What happens if you touch mr blacklots Pokemon statue in platnium?

You are referring to the Mr. Stone statue in Pokémon Platinum, not "Mr. Blacklots." This statue is located in the Veilstone Department Store, and nothing happens when you touch it.

It is simply a decorative statue that adds to the environment of the store. It doesn't have any hidden function or trigger an event.

Perhaps you're thinking of something else? Let me know if you can recall any more details about what you're thinking of, and I can help you further.
