Has anyone else noticed what looks like a break away wall in the first area right below the mouse with a gun? I wonder if you can find a way to break through, or if was just a joke by the ever comedic programmer...
have them both pushing against one wall, then wait for the apple to hit you, you will disappear for second, then the elephant facing the other direction will appear IN the floor, run to the other wall and do it again!
when I first started I was going to complain about it being too easy what wit you controlling the almighty flying brick, but the narrow tunnels fixed that, so good game
