Chinese Zodiac and Lunar Year can be called very close friends. In Eastern cultures, each lunar year is assigned to one of the twelve animals in Chinese zodiac. The animal (or rather a mascot) of this year is the pig. So, my question in this question is:
How to draw a (lovely) pig in LaTeX?
I found a very beautiful picture on TeXample:
% Author M.R.C. van Dongen
% Draw parameterised pig.
% This code can/should be improved by using the pgfkey library.
\documentclass{minimal}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage{keyval}
\makeatletter
% We're not using pgfkeys, and we've chosen to use keyval
% for option parsing. The following define the keys for a
% pig keyval family. The main purpose of the keys and
% default values is that we want to be able to draw pigs
% with predefined colours for certain parts and predefined
% scaling factors for line thickness.

However, I wish to see more pigs here, especially with other familiar animals, like lions, ducks, marmots, bears, rabbits, birds, donkeys, or penguins.
I am also looking for a tikzlings pig!
