Graffiti

An example of graffiti, as seen in the credits of Splatoon.

Graffiti are a common element in Inkopolis and Splatsville, being present in all main hubs, Story Modes and all stages. They consist of official designs and player-made drawings made via the mailbox. If a player is not connected to the internet or disables posts in the Options menu (or in any case in Splatoon following Miiverse's closure), graffiti that would normally depict player-made drawings instead shows predetermined illustrations.

Official designs show up in all sorts of forms, some of them being stickers, posters or spray painted. They can appear on the ground, buildings, objects, loading screens and menus among others. Many of these designs reoccur throughout multiple games.

Splatoon

Players could create drawings in the form of Miiverse posts that then showed up in game. This feature was removed upon Miiverse's closure. They appeared on specific billboards, and during Splatfests they appeared on banners, neon signs, fireworks and the back of the Squid Sisters' trucks. Walking up to an Inkling in the Inkopolis Plaza displayed their drawing (if one was created) above their head in a speech bubble. A player is able to hold to focus on a specific player-made drawing, which allows them to respond to it with "Yeah!".

Splatoon 2

Player-made drawings are now created fully in game, and can be shared online through a Twitter or Facebook account linked to their Nintendo account. A player has to post their drawing on at least one of those sites for it to show to other players. Similarly to Splatoon, player-made drawings show up on specific billboards and as speech bubbles above Inklings and Octolings. They additionally show up as small cards during Splatfests, and banners held by Inklings and Octolings. A player is able to hold to focus on a specific player-made drawing, which allows them to respond to it with "Fresh!". This can also be done directly through the speech bubbles.

Splatoon 3

Player-made drawings function almost identically to Splatoon 2. During Splatfests, they also additionally appear in the sky through drone shows.

Trivia

• Despite the closure of Miiverse, posts from it still appear as graffiti in Splatoon in the Battle Dojo stages and Octo Valley missions that are based on multiplayer stages.
• According to a developer interview, jellyfish are known to create a large amount of graffiti. This may mean that they are responsible for some of the graffiti in Inkopolis.
• Some stickers that appear as Easter eggs depict characters from other Nintendo franchises, such as Bloopers and Octoroks.
• The graffiti in stages is colored to match the neutral color of the two ink colors in the current battle.
• There are different variants of the small cards that depict graffiti in Octo Valley and Octo Canyon to those found in Inkopolis. In the Octo Expansion, round versions of these cards appear.
