If I remember right, I had this phrase stuck in my head. (Waka was clearly in control of my brain that day. (Night?)) So I drew Waka, added the words, and then went absolute batshit with text warps, gradients, 70's fonts, and stock textures.
Ushiwakamaru is his name in the Japanese version of the game and it had a better rhythm than just Waka, so that's why that is.
