Easiest cheat to restore Zombie back to FULL HEALTH!

This is the easiest way to restore full health back to your zombies and there's no possibility that it will turn your cafe to green. I have tried it and it works..just follow the below steps:

Step 1: Go to your iPhone settings and turn off all notifications.
Step 2: Turn auto lock to never.
Step 3: Head to zombie cafe and close your cafe door.
Step 4: Put all your zombies to rest for half an hour and BAM! all your zombies are restored to full health and your cafe will NEVER turn green.

I recommend charging your iphone while doing this because it will sap lots of power away. Rinse and repeat~ =) Enjoy your zombies
