Awkward sound??? cheats for Luigis Mansion

Awkward sound???

I was in area 3 when a boo escaped into a hallway(it was a dark hall). Then a yellow bowling ghost appeared so I went to catch it. When I caught it some random music played that reminded me of wiggler from Super Mario Sunshine. After a couple of seconds the music stopped and the regular dark hallway music came back. Not sure what the requirements were but maybe the boo went through the wall to another room when I caught the bowling ghost.
