Vigilant staff have picked up signs that the creatures appear to be gathering around a PokeStop at the building.
Even more alarming is these creatures (we understand the scientific name is Pokémon) don't seem to be responding to our usual pest traps, and we seem unable to capture them.
The museum conservator said:
"These things have me baffled. I have tried using all of our usual pest-control methods, but they are still there, sitting on our museum objects. I don't know what else to do! This is a museum emergency - I've never seen anything like this before."
We need your help!
Please, come to the museum and help us capture all of these Pokémon.
