Halo 3-Please help me get the last 2 skulls I need!?

Question

All I need is the Cowbell Skull and Catch skull, but to get the catch skull I need to beat campaign on normal or harder. I have to beat 2 more levels and then I can get the skulls by myself. If you can help me send me a friend request.
