This terrifying purple creature stands tall, and is ready for adventure! His two long horns are sticking out from the top of his head and a long, snakelike tongue hangs from his mouth. His small yellow eyes peer out from underneath his cape, which is black with a white collar. The poor monster is even armed with a large, imposing black stick in his left hand! For the coloring, I'd use brighter shades of purple for the monster, a golden or yellow for the eyes, and perhaps a darker shade of purple to match the sticks. For the cape and collar, warm shades of beige, cream or white will bring out the contrast. Finally, his horns could be a hue of orange or red to give them an extra pop.
