Ahhh.... I think this is the one where spikes fly out of the wall and impale you? [Okay, so there are some rusty bell things here on the wall. They don't sound great, but they are somewhat musical, and better than anything he's found so far. They were probably some other poor sap's attempt - which may be a bad sign, if you think about it. He yanks them down anyway.] Or the ceiling drops and crushes you. Should be quick either way.
