Poland is one of the country skins in Agar.io. It can be used by typing "Poland" in the nickname box before the game begins. Then the player's cell will become strangely the inverse of the flag of Poland, or become like the Indonesian or Monaco's flag. It also has two eyes, so it is really the Polandball skin.
- The skin has two eyes on the top and its flag is upside down, which is a reference to the web comic and meme Polandball.
- This is the first skin added to Agar.io.
- In 2016, Polish skin was removed for unknown reasons, for 2 days.
- It's the only country skin which don't uses the real flag of the country.
