So guys, I'm back today and with my return I have for you a lesson on another and final character from Hey Arnold!. Here is a lesson on how to draw Phoebe, step by step. Phoebe Heyerdahl is actually Helga's best friend as well as the smartest kid in the class. She is also one of Arnold's smartest friends, and judging by the look on her face and her style, she needs all the friends she can get. Anyways, there is really not much to tell about Phoebe. All I can really do is show you how to draw her out. I shall return so don't go anywhere far.
