First appearance "Kidonia"

Kidonia was a Micronation founded by Arthur, Francine, Brain, and Buster as a child-exclusive place. It is currently dissolved and the land has been reverted to the Tree House.


After getting tired of being told to do chores, Arthur and the gang decided to make a country for children.


All of the residents moved away to their homes due to the following:

  • Francine left due to Buster's socks "stinking up the whole country".
  • The Brain left jealousy due to the mind reading contest.
  • Buster left due to a new rule. (Everything that is on the floor should be cleaned up, to be exact.)  
  • Arthur left due to Kidonia being deserted.


Oh dear Kidonia,
I pledge my loyalty,
Where kids have broke the chains
of parental tyranny.
Where chores are no more,
and fun is guaranteed, 
All hail Kidonia,
land where kids are free!


  • The Latin motto, "Ludus, Ludus, Ludus" translates to "Game, Game, Game" or "School, School, School".
  • Like most countries, Kidonia has a passport.
  • They also have their own currency.
  • If Kidonia would have still existed, their ccTLD would possibly be .kd
