Easter Egg: The Heart of the City.

If anyone has yet had the time to have a look at the Statue of Happiness, you'll want to go inside, and see for yourself, the lulz that beats steadily.
That's right, the Statue of Happiness has a beating heart, chained up inside. You have to climb pretty high, though. Worth it.
