Zoos. Though many of the greatest huntsmen and the cleverest menagerie-keepers spent years of their lives searching through the jungles in all weathers for pushmi-pullyus, not a single one had ever been caught. Even then, years ago, he was the only animal in the world with two heads.
Well, the monkeys set out hunting for this animal through the forest. And after they had gone a good many miles, one of them found peculiar footprints near the edge of a river; and they knew that a pushmi-pullyu must be very near that spot.
Then they went along the bank of the river a little way and they saw a place where the grass was high and thick; and they guessed that he was in there.
So they all joined hands and made a great circle round the high grass. The pushmi-pullyu heard them coming; and he tried hard to break through the ring of monkeys. But he couldn't do it. When he saw that it was no use trying to escape, he sat down and waited to see what they wanted.
