Can you sneak like a poltergeist?

The way pace around the castle . . . wreaking mayhem in whatever crosses their path. It wasn't an easy job but it certainly wasn't the most demanding. Of course it shouldn't be demanding because it wasn't like poltergeists got paid; actually they were generally shunned from wherever they resided. It was a wonder Hogwarts had allowed one for so many years, but now, even in the mayhem wreaked, their poltergeist was a part of the castle.

Pacing . . . throwing dungbombs . . . shrieking at students . . . Peeves was practically at home.
