This cartoon character is the lead guitarist and vocalist of the band that shares his name; CMYK! Although he calls the second dimension his home, he has a habit of finding his way into the third, either by escaping to there himself, or by making new fans and transforming those that resonate with his sounds, outlining them with ink and flattening them into a perfectly two-dimensional form as they become a wolfdog toon themselves. And once CMYK has entered the third dimension, he has a habit of 2D-ifying anything he can get his gloved paws on, and even the space around him can end up compressed. You might even end up as a new bandmate for him!
