Vivienne escaped from her room as a small child and was found and raised by wild animals. As she grew up, she learnt to speak to her animal friends through pictures. It was through drawings that she made her first demand for food. Fried chicken, to be more specific. She then asked for kittens (not the fried kind...the alive and meowing kind, obviously).
Her forest friends brought her everything she drew and went on every adventure she illustrated. From then on her goal in life was decided: she had to learn how to draw everything.
While Vivienne now lives amongst humans again, she will never forget her many friends in the forest. Sometimes she still runs away to go on adventures with them.
