In this tutorial, I’m going to show how to draw Petunia Pig from The Day the Earth Blew Up. This version has 21 steps and works well if you’re familiar with basic cartoon proportions. Petunia’s current look from the film is a bit more detailed than her classic one.
Key Features of Petunia’s Movie Appearance
- Short black bob haircut with a large purple bow on the side
- Wide expressive eyes and lashes
- Pig-like snout and small ears
- Lab coat with pockets and collar
- Purple dress underneath the coat
- Flat feet and cartoon-style black-outlined shapes
You could try drawing Porky Pig or Daffy Duck from the same movie next. Their designs match well in style and theme.
Understanding the Visual Steps
- Red Color: current line to draw
- Black Color: already completed lines
- Grey Color: rough construction sketch for proportion reference





















Now that you know how to draw Petunia Pig, head over to the pinned post on SketchOk’s Pinterest board and share your finished sketch in the comments. That’s where a lot of people in the community drop their drawings, swap tips, and talk through what worked or what gave them trouble. If you prefer watching over reading, check the SketchOk YouTube channel too, since video versions of some guides are posted there.
