1. A chess game. Not just a chess set, mind, but a chess game. It must be in motion. At all times.
2. A life-size model of a baby giraffe. No real toys shall be permitted. Oh, okay, you can have the stuffed monkeys but JUST TWO! And only on the condition that they have to sit and watch the chess game. Which must be in motion. At all times.
3. A giant bullet hole. It’s left there as a warning and a memento. Of what happened to the last toddler who tried to stop the chess game.
