Start by drawing an oval shape for the turtle shell.
Draw another small oval for its head and small circles for its eyes.
Next draw legs (well flippers) start with a first pair of semi-circle and then make another one. Also add a small triangle at the tip of the oval as a tail.
Last but not least, draw a few lines along the oval shape. This will give the turtle's shell some texture.
