On level 1 when you get the first key, go through the
first gate. You will see groups of ants marching. Allow them to
see you, then roll up to a wall of grass on the side of the land.
Let the ants hit you, and if you are lucky, you will fall through
the wall and get on the other side. There will just be a path
going around the border of the land. In the background you will
see faces. After awhile the game will return to the menu screen.
