Monkey

Martin ran around in a circle chasing the dog and its tattered monkey. The dog's monkey was called 'monkey'. He liked to imagine that the dog called the monkey 'monkey' too. The game was simply to run around and try and get the monkey from the dog. The dog would never release the t, only drop it teasingly on the ground for a moment then tearing off gleefully.
The dog destroyed every toy but Monkey. Monkey was tattered but largely intact. Sometimes the dog would suckle Monkey like it was it's mother. He had to stop hanging out in the park and playing with other people's dogs.
