This trophy is unlocked during Chapter 11. As you are walking through the market you will get to a point where you will hear a woman shouting about apples that are for sale. She can be found in the middle of the market. Head over to her and purchase an apple from her. Nate will start eating the apple as he is walking on talking to Sully. You will eventually get to a point where there will be a man who has a pet Lemur. Interact with the Lemur and then walk away. When you walk off the Lemur will chase after you and steal your apple. The trophy will pop after he steals your apple.
Play with the lemur in the market and let it steal your apple
