When you touch it, it turns out that it was just a loose brick. The
brick falls to the floor. However, you notice that when it did, it
loosened up a bunch of other bricks.
"Dave!" You call. "I think I found a way to get out of
here! These bricks are loose!"
Dave comes over and helps you take the bricks away at they come loose.
Soon there's a small hole.
"No more bricks will come loose!" you say. "It's only
big enough for one of at a time! Who goes
first?"
You go for the brick on the right wall.
