This amigurumi "Garden Variety Zombie" from Plants vs. Zombies was made based on the boy pattern in the book Complete Idiot’s Guide To Amigurumi, with modifications to the head, the leg and the clothes. The head has to be adjusted to account for the gaping mouth and bulging eyes. The body has the addition of a vest, jacket and tie, the clothing edges are "ragged" and the pants have part of a leg completely "ripped" off to expose part of the leg and knee.
The orange cone is removable and he has little tufts of hair scattered all over the top of his head (though you only see a couple in the photos).
The last photo has another zombie I made based on the first one. You can see it's slightly different - but I prefer the slightly smiling look the original zombie has. I'll have to make a third zombie to attempt making a pattern.
