Step 6: Below Bowser Jr.'s body, draw two short, diagonal lines each with a small oval at the end. These are guides for his feet.
Step 7: That’s it for the initial sketch! You have the basic Bowser Jr. shape, so now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 8: Draw the lower part of Bowser Jr.'s face by using the initial lines as guides. Curve the top part to give him his nose and add two little drop-like shapes for his nostrils.
Step 9: Below Bowser Jr.'s nose, draw his mouth. The shape of the mouth is similar to a crescent moon on its side. Inside the mouth on the top side, draw a triangle for his single tooth. Also draw a curved line inside for his tongue.
Step 10: Above his muzzle draw two small circles and shade them in to create his eyes. Leave a tiny bit unshaded to represent glare. Above Bowser Jr.'s eyes, draw two thick curved shapes with jagged edges as his eyebrows.
