The Menu Item block is a script block which was added on Fancade 1.6 beta. When it is executed at least once it activates the shop system adding a shop to the game which is only accessible when you win or lose the game. The main use of this script is to add items to a shop which should ONLY be done once per item. To learn how to use it, see [here](https://www.fancade.com/wiki/Script/How%20to%20use%20the%20shop%20system%3F.md).
