Graffiti

Graffiti is found all over Inkopolis, from every stage to the Plaza. It is shown in the form of Miiverse drawings, stickers and scribbles on the ground, billboards and on walls. They can be found on all stages and in Inkopolis Plaza. During Splatfests, they can be seen on the back of the two trucks Callie and Marie dance on top of, on banners, on neon signs, and in the sky possessing the form of what appears to be fireworks.
