Draw a Brown Bear with python Turtle: Shapes, Fill and Layering

In ,
Draw a brown bear character with python Turtle using circles, filled shapes, coordinates, headings, and layered pen movement in a beginner-friendly example.

After sharing a video of this Turtle drawing, several people asked for the code. It uses only python’s standard turtle module.
