Sure! Here's how you can draw a simple unicorn using TikZ in LaTeX. The following code creates a basic illustration of a unicorn using shapes like ellipses, circles, and lines.

First, make sure to include the necessary TikZ libraries:

```latex
\documentclass[tikz]{standalone}
\usetikzlibrary{decorations.pathmorphing}
```

Now, here's the TikZ code to draw the unicorn:

```latex
\begin{document}
\begin{tikzpicture}

% Body
\draw [fill=white, draw=black] (0,0) ellipse (2cm and 1cm);

% Neck
\draw [fill=white, draw=black] (1,0.5) -- (1.5,2) -- (2,0.5) -- cycle;

% Head
\draw [fill=white, draw=black] (1.5,2) circle (0.5cm);

% Horn
\draw [fill=yellow, draw=black] (1.7,2.5) -- (1.85,3.2) -- (2,2.5) -- cycle;

% Ear
\draw [fill=white, draw=black] (1.35,2.75) -- (1.5,3.1) -- (1.65,2.75) -- cycle;

% Legs
\draw [line width=2pt] (-1,-1) -- (-1,-2);
\draw [line width=2pt] (0,-1) -- (0,-2);
\draw [line width=2pt] (1,-1) -- (1,-2);
\draw [line width=2pt] (2,-1) -- (2,-2);

% Tail
\draw [line width=1pt, red, decorate, decoration={snake, segment length=5mm, amplitude=2mm}] (-2,0) -- (-3,-1);

% Mane
\draw [line width=1pt, red, decorate, decoration={bumps}] (1.3,2.5) -- (1.7,2.5);

% Eye
\fill (1.55,2.1) circle (0.05cm);

\end{tikzpicture}
\end{document}
```

### Explanation of the Code:

- **Body**: An ellipse centered at `(0,0)` representing the unicorn's body.
- **Neck**: A triangle connecting the body to the head, starting from `(1,0.5)` up to `(1.5,2)` and back down to `(2,0.5)`.
- **Head**: A circle centered at `(1.5,2)` with a radius of `0.5cm`.
- **Horn**: A triangle above the head, filled with yellow color, representing the unicorn's horn.
- **Ear**: A smaller triangle to the side of the horn to represent the ear.
- **Legs**: Four lines extending downwards to represent the legs.
- **Tail**: A wavy red line starting from the back of the body, using the `snake` decoration.
- **Mane**: A decorative red line on top of the neck using the `bumps` decoration.
- **Eye**: A small filled circle on the head to represent the eye.

Here's the full LaTeX document including the preamble and necessary packages:

```latex
\documentclass[tikz]{standalone}
\usetikzlibrary{decorations.pathmorphing}

\begin{document}
\begin{tikzpicture}

% Body
\draw [fill=white, draw=black] (0,0) ellipse (2cm and 1cm);

% Neck
\draw [fill=white, draw=black] (1,0.5) -- (1.5,2) -- (2,0.5) -- cycle;

% Head
\draw [fill=white, draw=black] (1.5,2) circle (0.5cm);

% Horn
\draw [fill=yellow, draw=black] (1.7,2.5) -- (1.85,3.2) -- (2,2.5) -- cycle;

% Ear
\draw [fill=white, draw=black] (1.35,2.75) -- (1.5,3.1) -- (1.65,2.75) -- cycle;

% Legs
\draw [line width=2pt] (-1,-1) -- (-1,-2);
\draw [line width=2pt] (0,-1) -- (0,-2);
\draw [line width=2pt] (1,-1) -- (1,-2);
\draw [line width=2pt] (2,-1) -- (2,-2);

% Tail
\draw [line width=1pt, red, decorate, decoration={snake, segment length=5mm, amplitude=2mm}] (-2,0) -- (-3,-1);

% Mane
\draw [line width=1pt, red, decorate, decoration={bumps}] (1.3,2.5) -- (1.7,2.5);

% Eye
\fill (1.55,2.1) circle (0.05cm);

\end{tikzpicture}
\end{document}
```

### Instructions to Compile:

1. **Save the Code**: Save the code above in a file named `unicorn.tex`.
2. **Compile the Document**: Use a LaTeX compiler that supports TikZ and the `decorations.pathmorphing` library. You can compile the document using the following command:

   ```bash
   pdflatex unicorn.tex
   ```

3. **View the Output**: This will generate a `unicorn.pdf` file with the drawing.

### Example Output:

When you compile the code, you'll get a simple illustration of a unicorn that looks like this:

![Unicorn Drawing](attachment:unicorn.png)

*(Note: Since we can't display images here, you'll need to compile the code to see the drawing.)*

### Customization:

- **Colors**: You can customize the colors by changing the color options in the `\draw` commands (e.g., `fill=white`, `draw=black`, `red`, `yellow`).
- **Line Styles**: Modify `line width`, add `dashed` or `dotted` styles as desired.
- **Decorations**: Explore different decorations in the TikZ library for the mane and tail (e.g., `coil`, `zigzag`).
- **Shapes**: Adjust the coordinates and dimensions to change the proportions of the unicorn.

### Additional Resources:

- **TikZ Package Documentation**: [TikZ & PGF Manual](http://mirrors.ctan.org/graphics/pgf/base/doc/pgfmanual.pdf)
- **TikZ Libraries**: For more decorations, you can include additional TikZ libraries using `\usetikzlibrary{<library name>}`.
