Zombies love brains. They need brains to stay active and help you progress in the game. Once you reach the Big Land, you'll see some zombie workers there. They will cut trees and stones, cook creepy recipes, collect weird items, and bring you zombastic collections if you give them brains! 

There are 2 ways to get brains: 
1. You can buy them at the Market. 
2. Tap the FREE BRAIN button and watch fun videos that give brains.
