In a zoo there was a monkey. The monkey carried a bag with a hole in it. This bag was magical. If you jump in it you go to a completely different world. The monkey only jumps into the bag when he needs to hide. Sometimes it is danger but sometimes it is just a game.
The bag is so dark that when you hit the floor of the world you don't no where you are.
The bag is so deep that if you dip your hand in you shall never feel the bottom.
Sometimes he jumps in and out.
