Step 16: Draw a long curved line under the horizontal construction line for the collar of Poof's onesie. Draw an X under the collar as extra detail on the the onesie.
Step 17: Darken the U-shaped arcs under Poof's body to create the covered feet. Draw line near the middle of the arcs for detail on the onesie.
Step 18: Darken the arc on the right to create Poof's other arm. Draw a line near the wrist for the sleeve and two smaller curved lines at the tip to separate the fingers.
Step 19: On top of Poof's head, draw a thick spiral line for his single curly hair. On the left side of the hair, draw Poof's crown. The crown basically consists of a W-shaped line with a straight line under it.
Step 20: That’s it! You now have a nice sketch of the cartoon character Poof from Nickelodeon's The Fairly OddParents. You can stop at this quick drawing for a rough, sketchy look or go for a more finished look by continuing to the next step.
