In The Land Of Oz the Scarecrow and his friend friends find themselves unable to escape from a horde of moving ants. Then they meet Dorothy who offers them advice regarding their quest. She tells them that it will take several days for all the ants to reach Emerald City as the way tunnels are built allows for movement in all directions. Also she says that once the last ant leaves then there is no turning back.
