These are the 3 basic shapes for creating cartoon characters in Adobe illustrator. The circle and the square are easy to create on your own, the oblong oval is the one beginners might have trouble with, so I created it for you.
Simply unzip the folder > Open the .ai file in illustrator > start creating
