This is my Pirate Monster:

• I started by generating a checkered background. I am a beginner in JavaScript, so I came up with a very "unelegant" way to create the pattern.
• Next, I defined a simple circle as the body of the monster.
• I added a 3-color radial gradient filling to the body, and a shadow behind it.
• Then I defined its main facial features (eyes, pirate patch, eyebrows, mouth, teeth, moustache).
• Finally, I added some animation to it by making the left eye move.
• I tested the final design in Safari, Chrome and Firefox and they all look the same.
