Sketch from my sketchbook on Zehndy in his third stage of rage. (XD) What he looks like when he's really pissed off without his bandanna, holes kinda open up where his eyes should be in the same fashion as his mouth does. And his tongue looks just like one of his tendrils, acts like one too.
His first rage stage is just when he's mad with his bandanna on, second it when his bandanna is folded and his mouth appears, third is this, when his bandanna is off and his eye spot/holes appear, fourth is when his rarely seen yellow eyes appear. If you see his real eyes, you're pretty much dead already. They only appear when he's really really really really REALLY mad.
