User blog:Drek'TharSuperSword/I don't understand what does the Blocked template mean

I mean, really. What's with those Wall-nut and Zombie picture on the Blocked template? I don't get the meaning of them.

Picture (if you don't know what the template looks like)



See? What do "Wall-nut with a zombies next to it" mean?

I don't get it at all. If someone can tell me then please leave me a comment.
