During level 1 when you get the first key, go through the first gate. You will see groups of ants marching. After allowing them to see you, 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. Eventually the game will return to the menu screen.
During level 3, take the second Taxi Bug out to the farthest point that ends in the water. On the right is a rock. Push the Taxi Bug so that it can go through the weed, then position it so it is slanted in the weed and facing somewhat off the rock. Get off the Taxi Bug and walk on the long narrow rock. Then, follow it until you can jump into a white world. There is nothing there but whiteness. You can roll on forever.
