Over and Over

You slowly step down into the unknown darkness- the opening in the floor. As you step in, you feel something slowly grab your foot and you think ot yourself,"This is the end...i'm really about to die." But lucky for you, your not yet dead. Instead, its just some sort of creature that you have never seen before slowly ripping at your legs. You frantically kick and shriek, "Get off of me you stupid animal!" Finally, after about 10 minutes of struggling, the creature blows up into some sort of greenish goop that makes you slide down sort of "dungeon". You think that you are ok, but then you realize that you have triggered some sort of trip wire on the way down and you shout,"UGGHH, why does this have to happen to me!". Next thing you know, you see a big boulder slowly hurling down at you.
What do you do?
