The Little Bakery of Horrors

You have just open a Little Bakery shop. 

A dream comes true! First customers are coming and you have a lot of things to do:
* Use the sourdough.
* Bake the bread.
* Sell the loafs for your new customers.

But remember!! You must feed the sourdough to keep it alive. To keep your business alive! Or it will become the worst zombie dough you have ever seen!
