Back to Licorice. He has a real thing for catnip. Unfortunately, he used a bit too much fertilizer. When you watch these images, note consistency. ALL areas of the plant grow.
ALL leaves get bigger.
The cat's expression changes, but in the last several frames, the eyes are as wide as they can be. Now, when cartooning, you could keep making them bigger and bigger. The first few frames, have the vines twine around the ears and legs. Do NOT cover up the face or eyes until the very LAST frames. I added color to Licorice's eyes in the first frame, because they were dull.
