The eyes are the only facial part a countryball has. There are several of them:

Happy

Can be seen in game and in lobby thing.

Scream

Can only be found in lobby and changing room thing when you hover over your character

Sad

These eyes can only be found when you lose a match and when you take damage.

Just another version of sad.

Bored or Something
