The problem is, I don't see any zombies. All I see is terrain and flowers. And the occasional cow/sheep.
Do I just need to keep looking? What am I looking for? How do I get the different types of blocks? I found some by hitting the sheep (or whatever they are) but the same thing didn't seem to work on trees or terrain.
Gah. I do enjoy the freedom of the game. But I need to do something soon or I just lose interest and quit.
