Bulgaria is a toilet

Recently a piece of art was created representing each of the countries in the EU. That is the European Union for all those who don't give a shit about europe. Anyways, each country was portrayed in its own stereotype, in the Entropa Display, which i personally find hilarious.
So, what is the stereotype of Bulgaria you may ask?

Apparently its a toilet. Heres a picture.

Unfortunately, political correctness is still a virus that plagues the world. The EU has censored this piece of art by covering it with a black cloth. :(
