An egg
From NSwiki, the NationStates encyclopedia.
"An egg" is most famous for playing a training match against NEWI Cefn Druids after the third Cup of Harmony in Brazillico. And winning 1-0.
It entered World Cup 13, hoping that it could maintain this for, but against real footballers, it didn't put up much of a fight. It is still a legend in Druidan folklore tothis day.
