short audio clips for iphone game needed

This is for a game called "link" which you can read more about here: [login to view URL] I need short audio clips in MP3 format of these things: 2 second clip of a truck-load or train-load of wood lumber falling over. 2 second clip of a train "sputtering out" - i.e., losing steam and essentially stalling. This can probably be the same as a large truck stalling/dying. 2 second clip of a large metal container bursting open, and oil "glugging" out. 1 second mp3 of: A couple of lions roaring... ideally a roar indicating that they are dying or in pain. 2 second mp3 of: A train car full of boxes falling over... i.e., the boxes cracking and tumbling out of the train car. I'd like some scream samples, too. I'm looking for screams that sound like there are about 5 - 10 people, and they should be as close to 3 seconds in length as possible. If you can upload 5 such clips that would be helpful. The idea is that these audio clips are the "train crashing" audio clips for my game.
