Upon entering, Centres of crop circles will take the player to Puro-Puro, where they can participate in the minigame Impetuous Impulses.

A permanent crop circle can be found in the wheat field in Zanaris. There is also another crop circle that will change locations approximately every 15 minutes.

The music which plays while standing near a crop circle.


When a player nears an active crop circle, the game music changes to a variation of "Impetuous". The actual notation of unlocking the song will not be reflected on the music interface until the player actually travels to Puro-Puro.

Sister crop circle locations[edit | edit source]

It should be noted that the wheat field that contained the crop circle with which you entered Puro-Puro, will also be the wheat field that you will be teleported back to when you leave Puro-Puro. This will happen even if the crop circle has disappeared.

Trivia[edit | edit source]

  • Crop circles refer to the belief that aliens leave crop circles when they land in crop fields.
  • There is also a belief that a crop circle is an ancient language used by aliens.
  • When a crop circle disappears, an impling may try to get through it before it leaves. If it doesn't make it, it will shout "Impulus impling brothers!"
