The Grey Grumbles’ word balloons are jagged, colored like their skin color, but using the color of their eyes as the color of the text, with a black background. They also speak in the Monochrome alphabet, and this is the pretty clearly hand lettered here. I always end up making things bigger when I hand letter them, because I tend to draw with wide lines anyway, so it works out pretty well for creepy little monsters who scream all the time.
