This duck got built up with ceramics and dark energies so it could defend the doors of evil with it's power, but it's head is so hollow that he lacks common sense for common sense

I got this idea for two reasons:

1. I went to a store of ceramics searching for dishes and pots, and I saw many cool things.
2. While I was driving, I began thinking about ducks (dunno why exactly) and I stayed with that.

He's made of blue ceramics, nephrite, marble, granite and normal ceramics.
