Draw a Nose with a Bezier Curve
Problem Statement:

The pre-placed blocks draw the face. Add a Bezier curve block from the drawing blocks to create the nose. The first and last x and y coordinates determine the starting and end points of the curve. The middle coordinates guide the shape of the curve. Experiment with different coordinates to see how it works!
