Graffiti

Graffiti is found all over Inkopolis, from every stage to the Plaza. It is shown in the form of Miiverse drawings and stickers which sometimes depict other Nintendo characters, such as Bloopers or Octoroks.

Trivia

 * Miiverse graffiti still appears in the Battle Dojo stages and the Octo Valley levels in online stages.
 * Some, if not all, graffiti in Inkopolis Plaza is implied to be made by jellyfish; as stated in a developers' interview, jellyfish are known to create a large amount of graffiti.
